Homer Ferguson, 94, a former U.S. senator and ambassador to the Philippines who was a senior judge on the U.S. Court of Military Appeals, died of heart ailment Dec. 17 in his home in Grosse Point, Mich.

A Republican, Sen. Ferguson represented Michigan in the Senate from 1943 to 1955. During those years, he gained a reputation as an investigator, an outspoken foe of communism, and as a critic of the Senate's bipartisan foreign policy. He served on the Foreign Relations and Appropriations committees and was elected chairman of the Senate Republican Policy Committee in 1953.

He was defeated for reelection in 1954 by Patrick V. McNamara (D-Mich.). Sen. Ferguson then spent a year as ambassador to the Philippines before being named to the Court of Military Appeals in 1956. He took senior judge status in 1971, and moved to Grosse Point in 1977.

Sen. Ferguson was a native of Harrison City, Pa., and a 1913 graduate of the University of Michigan law school. He engaged in the private practice of law from 1913 to 1929, then served as circuit judge of the circuit court for Wayne County, and was a member of the faculty at the Detroit College of Law before winning election to the Senate in 1942.

Survivors include his wife of 69 years, the former Myrtle Jones, and a daughter, Amy Margaret Beltz, both of Grosse Pointe; six grandchildren, and 19 great-grandchildren.
