                      listed on the New York Stock Exchange

                               TO THE STOCKHOLDERS

For  the  six  months  ended  June  30,  2004,  the  investment  return  to  our
stockholders  was 1.7% (assuming  reinvestment of all dividends).  The net asset
value  per  Common  Share  increased  2%.  By  comparison,  the  rate of  return
(including income) for our benchmark, the Standard & Poor's 500 Stock Index, was
3.4%. For the twelve months ended June 30, 2004, the return to our  stockholders
was 12.1% and the  return on the net asset  value per  Common  Share was  13.9%;
these  compare  with a return of 19% for the S&P 500.  During each  period,  the
discount at which our shares traded increased  slightly and at June 30, 2004, it
was 10.4%.

As set forth in the accompanying  financial statements  (unaudited),  as of June
30,  2004,  the  net  assets  applicable  to the  Company's  Common  Stock  were
$982,924,500, equal to $33.65 per Common Share.

The increase in net assets  resulting  from  operations for the six months ended
June 30, 2004 was  $17,435,102.  During this period,  the net  realized  gain on
securities sold was $13,036,174 and the increase in unrealized  appreciation was
$7,846,728.  Net  investment  income  for  the six  months  was  $2,502,200  and
distributions to Preferred Stockholders amounted to $5,950,000.

During  the six  months,  577,300  shares of the  Company's  Common  Stock  were
repurchased for $17,581,159 at an average discount from net asset value of 9.7%.

Equity  markets  continue to trade in a narrow range  despite  healthy  economic
growth and robust corporate  profits.  Progress appears to be constrained by the
prospect of a less  accommodating  Federal  Reserve and rising  interest  rates.
Further  reductions in portfolio cash reflect  increased  investment in equities
centered, in the main, on natural resources.

We are pleased to report that, on July 14, 2004, Ms. D. Ellen Shuman was elected
to the Board of Directors. She is Vice President and Chief Investment Officer of
Carnegie Corporation of New York and serves as a director or trustee of a public
company and several educational organizations. Ms. Shuman's familiarity with the
investment  management  process  and  knowledge  of  the  securities  regulatory
environment will be of great value in the deliberations of our Board.

We are pleased to announce the  Investors  Choice Plan, a direct stock  purchase
and sale plan sponsored and  administered  by our new transfer  agent,  American
Stock Transfer & Trust Company  (AST).  Under the Plan,  Stockholders  and first
time  buyers  will  have the  opportunity  to  purchase  and sell  shares of the
Company's  Common  Stock  directly  through  AST. In  addition,  the Plan allows
participants to deposit their GAM Common Stock  certificates  for safekeeping or
sale.  A  booklet  describing  the  provisions  of the  Investors  Choice  Plan,
including transaction fees and other expenses, can be obtained by calling AST at
1-800-413-5499,  calling the Company at  1-800-436-8401  or visiting our website

9                   NOTES TO FINANCIAL STATEMENTS (Unaudited)
--------------------------------------------------------------------------------
                           General American Investors

                       1. Significant Accounting Policies

General American Investors Company,  Inc. (the "Company"),  established in 1927,
is  registered  under  the  Investment  Company  Act of  1940  as a  closed-end,
diversified  management  investment  company.  It is  internally  managed by its
officers under the direction of the Board of Directors.

The preparation of financial statements in conformity with accounting principles
generally  accepted in the United States  requires  management to make estimates
and assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

Certain prior year financial statement items have been reclassified,  from Other
Comprehensive  Income  to a  reduction  of  Expenses  and  an  increase  in  Net
Investment Income, to conform to the current year presentation.

a. Security Valuation  Securities traded on a national  securities  exchange are
valued at the last reported  sales price on the last business day of the period.
Securities  reported on the NASDAQ  national  market are valued at the  official
closing price on that day.  Listed and NASDAQ  securities  for which no sales or
prices  are   reported  on  that  day  and  other   securities   traded  in  the
over-the-counter  market are valued at the last bid price  (asked price for open
short positions) on the valuation date.  Corporate  discount notes are valued at
amortized cost, which approximates market value.  Special holdings are valued at
fair value in the opinion of the Directors.  In determining  fair value,  in the
case of restricted shares,  consideration is given to cost,  operating and other
financial data and, where  applicable,  subsequent  private  offerings or market
price of the  issuer's  unrestricted  shares (to which a 30 percent  discount is
applied).

b.  Short  Sales The  Company  may make  short  sales of  securities  for either
speculative or hedging purposes. When the Company makes a short sale, it borrows
the securities  sold short from a broker;  in addition,  the Company places cash
with that broker and securities in a segregated account with the custodian, both
as collateral for the short  position.  The Company may be required to pay a fee
to borrow the securities and may also be obligated to pay any dividends declared
on the  borrowed  securities.  The Company  will  realize a gain if the security
price decreases and a loss if the security price  increases  between the date of
the  short  sale  and the  date on  which  the  Company  replaces  the  borrowed
securities.

c. Federal Income Taxes The Company's  policy is to fulfill the  requirements of
the Internal  Revenue Code applicable to regulated  investment  companies and to
distribute substantially all taxable income to its stockholders. Accordingly, no
provision for Federal income taxes is required.

d. Indemnifications In the ordinary course of business,  the Company enters into
contracts  that contain a variety of  indemnifications.  The  Company's  maximum
exposure under these arrangements is unknown.  However,  the Company has not had
prior claims or losses pursuant to these indemnification  provisions and expects
the risk of loss thereunder to be remote.

e.  Other  As  customary  in  the  investment   company   industry,   securities
transactions   are  recorded  as  of  the  trade  date.   Dividend   income  and
distributions to stockholders are recorded as of the ex-dividend dates. Interest
income,  adjusted for  amortization of discount and premium on  investments,  is
earned from  settlement  date and is  recognized on the accrual  basis.  Cost of
short-term investments represents amortized cost.

                   2. Capital Stock and Dividend Distributions

The  authorized  capital stock of the Company  consists of 50,000,000  shares of
Common Stock,  $1.00 par value, and 10,000,000 shares of Preferred Stock,  $1.00
par value, of which 29,211,963 shares and 8,000,000 shares,  respectively,  were
outstanding at June 30, 2004. On September 24, 2003, the Company issued and sold
8,000,000  shares  of its  5.95%  Cumulative  Preferred  Stock,  Series  B in an
underwritten offering. The Preferred Shares are noncallable for 5 years and have
a liquidation preference of $25.00 per share plus an amount equal to accumulated
and unpaid dividends to the date of redemption.  The  underwriting  discount and
other  expenses  associated  with  the  Preferred  Stock  offering  amounted  to
$6,700,000  and were  charged to paid-in  capital.

The Company is required to allocate  distributions  from long-term capital gains
and other  types of income  proportionately  among  holders  of shares of Common
Stock and  Preferred  Stock.  To the  extent  that  dividends  on the  shares of
Preferred  Stock are not paid from long-term  capital  gains,  they will be paid
from ordinary income or net short-term  capital gains or will represent a return
of capital.

Under the Investment Company Act of 1940, the Company is required to maintain an
asset coverage of at least 200% for the Preferred  Stock. In addition,  pursuant
to the Rating Agency  Guidelines,  the Company is required to maintain a certain
discounted  asset  coverage for its  portfolio  that equals or exceeds the Basic
Maintenance  Amount  under  the  guidelines  established  by  Moody's  Investors
Service,  Inc. The Company has met these  requirements since the issuance of the
Preferred  Stock. If the Company fails to meet these  requirements in the future
and does not cure such  failure,  the Company may be required to redeem in whole
or in part,  shares of Preferred Stock at a redemption price of $25.00 per share
plus  accumulated and unpaid dividends  (whether or not earned or declared).  In
addition,   the  Company's   failure  to  meet  the  foregoing   asset  coverage
requirements  could  restrict  its ability to pay  dividends on shares of Common
Stock and could lead to sales of portfolio securities at inopportune times.

The holders of Preferred  Stock have voting  rights  equivalent  to those of the
holders of Common Stock (one vote per share) and, generally,  vote together with
the holders of Common Stock as a single class.

At all times, holders of Preferred Stock will elect two members of the Company's
Board of Directors and the holders of Preferred  and Common  Stock,  voting as a
single class,  will elect the remaining  directors.  If the Company fails to pay
dividends  on  the  Preferred  Stock  in an  amount  equal  to two  full  years'
dividends,  the  holders  of  Preferred  Stock  will  have the  right to elect a
majority of the  directors.  In  addition,  the  Investment  Company Act of 1940
requires that approval of the holders of a majority of any outstanding Preferred
Shares, voting separately as a class, would be required to (a) adopt any plan of
reorganization  that would adversely affect the Preferred Stock and (b) take any
action  requiring a vote of security  holders,  including,  among other  things,
changes in the Company's subclassification as a closed-end investment company or
changes in its fundamental investment policies.

The Company  classifies its Preferred Stock pursuant to the requirements of EITF
D-98,  Classification  and Measurement of Redeemable  Securities,  which require
that  preferred  stock for which its  redemption  is  outside  of the  company's
control should be presented outside of net assets in the statement of assets and
liabilities.

                          6. Operating Lease Commitment

In July 1992, the Company  entered into an operating  lease agreement for office
space  which  expires in 2007 and  provides  for future  rental  payments in the
aggregate amount of approximately  $5.6 million.  The lease agreement contains a
clause  whereby the Company  received  twenty  months of free rent  beginning in
December  1992 and  escalation  clauses  relating  to  operating  costs and real
property taxes.

Rental  expense  approximated  $149,000  for the six months ended June 30, 2004.
Minimum rental commitments under the operating lease are approximately  $505,000
per annum in 2004 through 2007.

In January 2003, the Company extended a sublease agreement  (originally  entered
into in March  1996)  which  expires  in 2007 and  provides  for  future  rental
receipts.  Minimum rental receipts under the sublease are approximately $254,000
per annum in 2004 through 2007. The Company will also receive its  proportionate
share of operating expenses and real property taxes under the sublease.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
--------------------------------------------------------------------------------
To the Board of Directors and Stockholders of
GENERAL AMERICAN INVESTORS COMPANY, INC.

     We have reviewed the  accompanying  statement of assets and  liabilities of
General  American   Investors  Company,   Inc.,   including  the  statements  of
investments  and  securities  sold short,  as of June 30, 2004,  and the related
statements of operations and changes in net assets and financial  highlights for
the  six-month  period  ended June 30,  2004.  These  financial  statements  and
financial highlights are the responsibility of the Company's management.

     We  conducted  our review in  accordance  with the  standards of the Public
Company  Accounting  Oversight  Board  (United  States).  A  review  of  interim
financial  information consists principally of applying analytical procedures to
financial  data, and making  inquiries of persons  responsible for financial and
accounting  matters.  It is  substantially  less  in  scope  than  an  audit  in
accordance with the standards of the Public Company Accounting  Oversight Board,
the objective of which is the  expression of an opinion  regarding the financial
statements taken as a whole. Accordingly, we do not express such an opinion.

     Based on our review,  we are not aware of any material  modifications  that
should be made to the interim financial statements referred to above for them to
be in conformity with  accounting  principles  generally  accepted in the United
States.

     We have previously  audited, in accordance with the standards of the Public
Company  Accounting  Oversight Board, the statement of changes in net assets for
the year ended  December 31, 2003 and financial  highlights for each of the five
years in the period then ended and in our report,  dated  January 14,  2004,  we
expressed an  unqualified  opinion on such  financial  statements  and financial
highlights.

ITEM 7. DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED-END
MANAGEMENT INVESTMENT COMPANIES.

                    General American Investors Company, Inc.

                      PROXY VOTING POLICIES AND PROCEDURES


     General  American  Investors  Company,  Inc.  (the  "Company")  is uniquely
structured as an internally managed closed-end  investment company. Our research
efforts,  including the receipt and analysis of proxy  material,  are focused on
the securities in the Company's  portfolio,  as well as  alternative  investment
opportunities.  We vote proxies relating to our portfolio securities in the best
long-term interests of the Company.

     Our investment  approach  stresses  fundamental  security  analysis,  which
includes  an  evaluation  of the  integrity,  as  well as the  effectiveness  of
management  personnel.  In proxy material,  we review  management  proposals and
management  recommendations relating to shareholder proposals in order to, among
other things, gain assurance that management's positions are consistent with its
integrity and the long-term  interests of the company. We generally find this to
be the case and, accordingly, give significant weight to the views of management
when we vote proxies.

     Proposals  that may have an  impact  on the  rights  or  privileges  of the
securities held by the Company would be reviewed very carefully. The explanation
for a negative impact could justify the proposal; however, if such justification
were not present, we would vote against a significant reduction in the rights or
privileges associated with any of our holdings.

Proposals   relating  to  corporate   governance   matters  are  reviewed  on  a
case-by-case  basis.  When they involve  changes in the state of  incorporation,
mergers or other restructuring,  we would, if necessary,  complete our review of
the rationale for the proposal by contacting company  representatives  and, with
few  exceptions,  vote  in  favor  of  management's  recommendations.  Proposals
relating to anti-takeover provisions, such as staggered boards, poison pills and
supermajorities could be more problematic.  They would be considered in light of
our  assessment  of the  capability of current  management,  the duration of the
proposal, the negative impact it might have on the attractiveness of the company
to future "investors," among other factors. We can envision  circumstances under
which we would vote against an anti-takeover provision.

     Generally,  we would vote with management on proposals  relating to changes
to the company's capital structure, including increases and decreases of capital
and  issuances  of  preferred  stock;  however,  we would  review  the facts and
circumstances associated with each proposal before finalizing our decision.

     Well-structured stock option plans and management compensation programs are
essential for companies to attract and retain high caliber management personnel.
We generally vote in favor of proposals relating to these issues; however, there
could be an occasion on which we viewed such a proposal as over  reaching on the
part of management or having the potential for excessive  dilution when we would
vote against the proposal.

     Corporations should act in a responsible manner toward their employees, the
communities in which they are located, the customers they serve and the world at
large.  We have  observed  that most  stockholder  proposals  relating to social
issues focus on a narrow issue and the corporate position set forth in the proxy
material  provides a well-considered  response  demonstrating an appropriate and
responsible  action or position.  Accordingly,  we generally support  management
recommendations  on these types of proposals;  however,  we would  consider each
proposal on a case-by-case basis.

     We take voting proxies of securities  held in our portfolio very seriously.
As indicated above, it is an integral part of the analytical  process at General
American  Investors.  Each  proposal and any  competing  interests  are reviewed
carefully on a case-by-case basis.  Generally, we support and vote in accordance
with the  recommendations of management;  however,  the overriding basis for the
votes we cast is the best long-term interests of the Company.

               repurchases program which began in March 1995.  As of the end of the period, June 30, 2004, there were 241,804 shares

ITEM 10. CONTROLS AND PROCEDURES.

Conclusions of principal officers concerning controls and procedures

(a) As of July 19, 2004, an evaluation was performed  under the  supervision and
with the  participation of the officers of General American  Investors  Company,
Inc. (the  "Registrant"),  including the principal executive officer ("PEO") and
principal  financial  officer  ("PFO"),  to  assess  the  effectiveness  of  the
Registrant's disclosure controls and procedures.  Based on that evaluation,  the
Registrant's  officers,  including the PEO and PFO,  concluded that, as of July
19, 2004, the  Registrant's  disclosure  controls and procedures were reasonably
designed so as to ensure:(1)  that  information  required to be disclosed by the
Registrant on Form N-CSR is recorded, processed,  summarized and reported within
the time periods specified by the rules and forms of the Securities and Exchange
Commission, and (2) that material information relating to the Registrant is made
known to the PEO and PFO as  appropriate to allow timely  discussions  regarding
required disclosure.

(b) There have been no significant changes in the Registrant's  internal control
over  financial  reporting  that occurred  during the  Registrant's  last fiscal
half-year  (the  Registrant's  second fiscal  half-year in the case of an annual
report) that has  materially  affected,  or is  reasonably  likely to materially
affect, the Registrant's internal control over financial reporting.

ITEM 11. EXHIBITS

(a)(1) The code of ethics  disclosure  required by Item 2 is not  applicable  to
this semi-annual report.
