Felix Riesenberg (1879-1939) was an American seaman, author, explorer, and engineer. Born and raised in Milwaukee, Wisconsin, Riesenberg graduated from the New York Nautical School (now SUNY Maritime College) in 1897, and obtained an engineering degree from Columbia University in 1913. He later returned to the New York Nautical School as superintendent from 1917–1919 and 1923–1924.
After graduating from the New York Nautical School, Riesenberg was part of the Coast and Geodetic Survey and served in the Naval Reserve until 1909. In 1906-1907 he participated in two of Walter Wellman's unsuccessful attempts to reach the North Pole by air. He also went on to serve as Chief Officer of the United States Shipping Board (from approximately 1915-1920). Riesenberg authored over 25 respected works of maritime fiction and nonfiction. His autobiography, "Living Again," was published in 1937.
Riesenberg died in 1939. In 2001, he was posthumously inducted into the US Merchant Marine Academy's National Maritime Hall of Fame.
