Between 1973 and 1976, he worked for the Securities Investor Protection Corp. where he was assistant vice president for finance. Since Februrary 1977, he had been an attorney with the trading and markets division of the Commodity Futures Trading Commission.

Mr. Snyder was a native of Michigan, and served as a tank commander in Europe during World War II. He was a graduate of Wayne State University and the University of Michigan's law school.

The family suggests that expressions of sympathy be in the form of contributions to the St. Catherine Catholic Church in Clarksville, Va.
