Recently I noticed a statue I hadn't seen before on Massachusetts Avenue NW at Sheridan Circle. I found that it was of Mustafa Kemal Ataturk
A plaque beside it says that the statue was paid for by private funds. It stands in front of the building that used to house the Turkish embassy.
The new Turkish Embassy is a couple of blocks away and on the other side of Massachusetts Avenue. It, too, has a statue of Ataturk--
I assume that the Turkish state paid for this one.
Excluding religious figures, I can think of only two other men represented by two or more outdoor statues in Washington. There are two statues of Abraham Lincoln: the immense seated figure at the Lincoln Memorial and a life-sized standing statue near the courts. There are four outdoor statues of George Washington: equestrian at Washington Circle and National Cathedral, standing in front of the Society of the Cincinnati and in George Washington University's University Yard. (There is also a large bust of Washington behind the Masonic Temple at 16th and S Streets NW.)
