                         A Closed-End Investment Company
                      listed on the New York Stock Exchange

                               TO THE STOCKHOLDERS
--------------------------------------------------------------------------------

For the nine months ended  September 30, 2004,  our  stockholders  experienced a
decrease of 0.3% on their investment in our Common Stock (assuming  reinvestment
of all  dividends).  The net asset value per Common  Share  increased  0.8%.  By
comparison,  the  rate of  return  (including  income)  for our  benchmark,  the
Standard  & Poor's  500 Stock  Index,  was 1.5%.  For the  twelve  months  ended
September 30, 2004,  the return to our  stockholders  was 9.7% and the return on
the net asset value per Common Share was 11.3%;  these  compare with a return of
13.7% for the S&P 500.  During  each  period,  the  discount at which our shares
traded increased slightly and at September 30, 2004, it was 11.2%.

As set  forth  in  the  accompanying  financial  statements  (unaudited),  as of
September 30, 2004, the net assets applicable to the Company's Common Stock were
$962,775,917, equal to $33.25 per Common Share.

The increase in net assets  resulting from  operations for the nine months ended
September 30, 2004 was $4,672,132.  During this period, the net realized gain on
securities sold was $13,296,001 and the decrease in unrealized  appreciation was
$3,420,819.  Net  investment  income  for the nine  months  was  $3,721,950  and
distributions to Preferred Stockholders amounted to $8,925,000.

During  the nine  months,  831,900  shares of the  Company's  Common  Stock were
repurchased for $24,966,772 at an average discount from net asset value of 10%.

While equity markets continue to trade in a narrow range, recent results suggest
that investors will be rewarded for holding the kind of quality companies,  with
strong earnings growth, that characterize  General American's  portfolio.  There
are,  of  course,  serious  impediments  to a  smooth  advance.  These  include,
conspicuously,  the war in Iraq  and  elevated  energy  prices,  as well as more
conceptual  issues such as too little savings and too much debt, all exacerbated
by the current political campaign. Nonetheless,  profits are continuing to grow,
albeit at a  decelerating  rate,  and,  in our view,  stocks  remain  attractive
relative to bonds.

The information about the Company, including our investment objective, operating
policies  and  procedures,  investment  results,  record of  dividend  payments,
financial reports and press releases,  contained at our website has been updated
through   September   30,   2004.   It  can  be  accessed  on  the  Internet  at

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 and written options) 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. OPTIONS The Company may purchase and write (sell) put and call  options.  The
risk  associated  with  purchasing  an option is that the Company pays a premium
whether or not the option is exercised. Additionally, the Company bears the risk
of loss of the premium and a change in market value should the  counterparty not
perform under the contract.  Put and call options purchased are accounted for in
the same manner as portfolio securities.  Premiums received from writing options
that expire  unexercised  are treated by the Company on the  expiration  date as
realized  gains from  investments.  The  difference  between the premium and the
amount paid on effecting a closing  purchase  transaction,  including  brokerage
commissions, is also treated as a realized gain, or, if the premium is less than
the amount paid for the closing purchase  transaction,  as a realized loss. If a
call option is exercised,  the premium is added to the proceeds from the sale of
the underlying  security in determining  whether the Company has realized a gain
or loss.  If a put option is exercised,  the premium  reduces the cost basis for
the  securities  purchased  by the  Company.  The Company as writer of an option
bears the  market  risk of an  unfavorable  change in the price of the  security
underlying the written option.

d. 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.

e. 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.

f.  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 28,957,363 shares and 8,000,000 shares,  respectively,  were
outstanding at September 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

                 2. CAPITAL STOCK AND DIVIDEND DISTRIBUTIONS -
                    (Continued from bottom of previous page.)

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.

Transactions in Common Stock during the nine months ended September 30, 2004 and
the year ended December 31, 2003 were as follows:
