These two busts, one of Sir Winston Churchill and the other of Franklin Delano Roosevelt (FDR) stand facing each other on the grounds of the FDR house, Springwood in Hyde Park, NY.
They’re by Oscar Nemon (born Neumann). At least the Churchill bust is by Nemon (I’m not entirely sure who was the sculptor for the FDR bust) and is described on his estate’s website as follows:
A recent bronze cast by the Nemon Estate was the magnificent bust of Sir Winston Churchill which stands opposite the bust President Franklin Roosevelt at the Franklin and Eleanor Roosevelt Institute, Hyde Park, New York.
The bust of Churchill was unveiled by his granddaughter Edwina Sandys (herself an artist and sculptor) and the sculptor’s daughter Aurelia Young on June 15 2007 during a conference whose theme was ‘Roosevelt & Churchill: The Legacy of Two Statesmen’.
