[1] Keck studied at the National Academy of Design and the Art Students League of New York with Philip Martiny, and was an assistant to Augustus Saint-Gaudens from 1893 to 1898.
In 1921 he was elected into the National Academy of Design as an Associate member and became a full Academician in 1928.
His work was also part of the sculpture event in the art competition at the 1932 Summer Olympics.
In 1913 Keck designed a memorial plaque that was cast from metal that had been salvaged from the USS Maine after it was raised in Havana harbor the previous year.
Over a thousand of the plaques were cast and they are spread unevenly all over the United States.
