Capt. Lamade was a naval aviator during World War II. In the early days of the conflict, he flew a catapult plane off the heavy cruiser Houston, which was sunk at the Battle of the Java Sea. He later commanded an air group on the carrier Hancock, also in the Pacific.

It was while serving aboard the Hancock that he earned the Navy Cross, the service's highest decoration for valor except for the Medal of Honor. He won it for leading a raid which resulted in the sinking of a Japanese light cruiser.

His other awards included the Distinguished Flying Cross and three Air Medals.

From 1969 to 1974, he was administrator of the Washington Home.

He then spent five years as administrator of the Wisconsin Avenue Nursing Home in Washington, retiring a second time in 1979.

Before joining the Washington Home, he worked for RCA's defense electronics services division.

Capt. Lamade was a past president of the National Capital Area Association of Homes of the Aging. He was a member of the Chevy Chase Club.

Capt. Lamade was a native of Williamsport, Pa. He was a 1932 graduate of the U.S. Naval Academy at Annapolis. He had lived in the Washington area since 1954.
