Marion Anthony Zioncheck (born Marjan Antoni Zajaczek; December 5, 1900 – August 7, 1936) was an American politician who served as a member of the United States House of Representatives from 1933 until his death.

But his tireless work on behalf of the New Deal often was overshadowed by his many personal escapades, which included dancing in fountains and driving on the White House lawn.

Beset by the press and by critics of Roosevelt's policies, Zioncheck became depressed and stated that he would not seek reelection to a third term in 1936.

[5] In his diary entry for April 30, 1936, Secretary of the Interior Harold L. Ickes recounted how Zioncheck had asked him to officiate at a wedding with his fiancée, Rubye Louise Nix.

[12] Zioncheck died after plummeting to the sidewalk from a window of his office on the fifth floor of the Arctic Building, at 3rd Avenue and Cherry Street in downtown Seattle, on August 7, 1936.

A note was found; it read, "My only hope in life was to improve the condition of an unfair economic system that held no promise to those that all the wealth of even a decent chance to survive let alone live.

His widow, as Rubye Nix Wilson, would later become a well-known artist, and was exhibited at the Museum of Modern Art and the Kennedy Center.
