Grover Aloysius Whalen (1886–1962) was a prominent politician, businessman, and public relations guru in New York City during the 1930s and 1940s.
Whalen was born on July 2, 1886 in New York City. Whalen was the son of an Irish immigrant father and a French-Canadian mother, who named their son after President Grover Cleveland, who was married on the same day that their child was born. His father, Michael Whalen, was a successful trucking contractor and a Tammany Hall supporter.
Grover Whalen attended DeWitt Clinton High School and afterwards studied law. He then joined the staff of John Wanamaker's department store, with which he would long be associated. He married Anna Dolores Kelly in 1913.
Whalen ran his father's ash and garbage disposal business for a time before becoming involved in politics, working for the election of John F. Hylan as Mayor of New York.
After Hylan became Mayor in 1918, Whalen was appointed to be Commissioner of Plants and Structures. In this position he supervised the city's transportation system. He also served as Hylan's Commissioner of Purchase and took part in greeting ceremonies, including the welcome of General John J. Pershing, commander of the American Expeditionary Forces, in 1919. In 1922, he proposed the creation of a radio station owned and operated by the city, a plan that came to fruition with the first broadcast of WNYC in 1924.
In 1924, Whalen left the Hylan administration to assist Rodman Wanamaker in the operation of the Wanamaker department stores, serving as general manager. Wanamaker named him Vice President of Operations for the American Trans-Oceanic Company, a new airline flying Curtiss seaplanes between New York and Florida.
