EARL AUSTIN JUNGHANS, 79, a retired Navy captain who later taught mathematics at Colby College in Maine and at Ascension Academy in Alexandria, died of cardiopulmonary arrest July 15 at his home in Alexandria.

Capt. Junghans served in the Navy for 34 years before his retirement in 1959. Most of his assignments were connected with naval aviation. A native of White Plains, N.Y., he graduated from the U.S. Naval Academy in 1929, attended flight training school and became a naval aviator in 1932.

He participated in the early naval actions of World War II at Wotje, Wake Island and Marcus Island in the Pacific and later was on the staff of the air commander for the Pacific Fleet.

After the war he was Naval commander on Wake Island, commander of the aircraft carrier Salerno Bay, and held several assignments relating to air naval intelligence. His final assignment before retiring was chief of the materiel management branch of the Industrial College of the Armed Forces at Fort McNair in Washington.

After retiring from the Navy, Capt. Junghans earned a master's degree in mathematics at Purdue University, then taught at Colby College until 1972, when he retired again. He taught calculus and U.S. history and government at Ascension Academy until 1976.

Survivors include his wife, Lida, of Alexandria; two sons, Peter A., of Alexandria, and Earl F., of Palo Alto, Calif.; one sister, Eleanor Vining of White Plains, and five granddaughters.
