A 100-year-old man who served in the Tuskegee Airmen, the all-black squadron of pilots during WWII, has died in his New York home.

Wilfred Defour passed away just before 9am on Saturday at his home in Harlem.

Defour was a part of a 16,000-strong squadron of black pilots and technicians that inspired African Americans across the nation to serve in the war.

He was found by his home's health aide in the bathroom of his Fifth Avenue home, police said.

An autopsy will take place to determine the cause of death. No criminality is suspected in his death. It's believed he died of natural causes.

Last month the centenarian was honored at a re-naming ceremony for a post office on Macombs Place in Harlem, which was retitled as the Tuskegee Airmen Post Office Building.

'We didn't know we were making history at the time,' Defour said during last month's post office renaming ceremony, according to the New York Daily News.

'We were just doing our job,' the aircraft technician said.

Defour served in the military then worked as New York Postal Service employee for 33 years afterwards, retiring as a Superintendent. After retiring he started a still-active real estate company in Harlem.

DeFour joined the Air Corps in 1942. He was assigned to the 366th Air Service Squadron, the 96th Air Service Group afterwards.

He was deployed to Italy where he worked as an aircraft technician at the 332nd FG at Ramitelli Airfield.

He helped paint the tails of his squadron's airplanes red, for which the group drew its Red Tails nickname.

He was discharged in December 1945 then returned to New York where he started his postal service career.

The Tuskegee Airmen was formed after civil rights advocates demanded African Americans train as pilots.

The men trained in Tuskegee Alabama and fought racism as they fought for their nation in the skies.
