He was born Alexei Mikhailovich Kremkov in Kazan, Russian Empire. He graduated from the naval academy in Saint Petersburg.
During World War I, he served in the Russian Navy on a destroyer.
Kremkov left Russia after the Bolshevik Revolution. He traveled east through China and Japan before reaching Egypt and finally France, where his name was romanised as Alexis Michel Kremkoff. In Nice, he drew cartoons for the magazine "Sur La Riviera" and then moved to Paris, where he drew cartoons for Le Matin, Fantasio Sourire and others.
In 1924, he immigrated to New York City, where he began contributing to The New Yorker. He was a long-time contributor to the Sunday drama section of The New York Herald Tribune. He painted theater sets as well, including Nikita Baliyev's Die Fledermaus.
In 1926, he was hired to create caricatures of Broadway and other celebrities at Sardi's Restaurant in New York City. Owner Vincent Sardi and Gard drew up a contract which stated Gard would produce caricatures in exchange for one meal per day at the restaurant.
He was naturalized as a U.S. citizen in 1940 (under the name Alexis Gard Kremkoff). During World War II, Gard served in the United States Navy as a specialist first class.
Gard continued to draw caricatures in exchange for meals until his death, ultimately creating more than 700 pictures. Today, the caricatures are housed in the Billy Rose Theatre Division of the New York Public Library for the Performing Arts.
On June 1, 1948, Gard collapsed on Seventh Avenue and 41st Street. He died as he was being transported to Roosevelt Hospital.
A memorial service was held for Gard at the Russian Orthodox Christ the Saviour Church, followed by a funeral mass the next day. He was buried at Arlington National Cemetery.
