Louis W. Shroyer, 93, a research analyst with the Air Force Department and a retired Air Force Reserve officer, died Jan. 9 at Sibley Memorial Hospital in Washington. He was a Bethesda resident.

He had complications from pneumonia, said a son, Andrew Shroyer.

During World War II, Mr. Shroyer was an aerial photo interpreter for the Army Air Forces in China. A few years after the war, he joined the Air Force Reserve and retired as a colonel in 1979. His decorations included the Air Force Commendation Medal.

As a civilian, he was a supervisory operations research analyst for the Air Force at the Pentagon until his retirement in 1980. He worked on war-gaming techniques and force planning procedures.

Louis Walls Shroyer III was a Baltimore native and a 1948 graduate of Washington and Lee University in Lexington, Va. A year later, he received a master’s degree in Asian history from the University of Illinois.

He was a past board president of the old Wesley Heights Community Club and served on the executive committee of the Washington Assembly, a social organization. He was also a volunteer at St. David’s Episcopal Church in Washington, a Boy Scouts scoutmaster and a member of Beta Theta Pi social fraternity.

Survivors include his wife of 64 years, Sally Ayres Shroyer of Bethesda; two sons, Louis Shroyer IV of Chevy Chase and Andrew Shroyer of Rockville; and four grandchildren.
