Retired Army Col. Glen S. Waterman, 63, a senior scientist with the Computer Sciences Corp. for the past 15 years, died Tuesday at Arlington Hospital after a heart attack.

Col. Waterman served with the U.S. 1st Infantry Division in North Africa in the early days of World War II and later participated in the invasion at Anzio, Italy, in January 1944.

Following the war he was a liaison officer and instructor at the Royal Signals School in England and worked on projects to standardize American, British and Canadian army communications equipment.

From 1954 to 1960 Col. Waterman directed the research divisions of Armed Forces Special Weapons Project and then the Defense Atomic Agency.

From 1962 until retiring two years later, he served at the Pentagon and worked on guidance programs for Defense communication satellite systems.

After joining Computer Sciences Corp., he contributed to studies on naval communications systems and continued to work on communication satellites.

He was a member of the Armed Forces Communications-Electronics Association.

Col. Waterman had lived in Arlington for more than 25 years and had been a volunteer for the Red Cross. He was a Mason and member of the Scottish Rite.

A native of San Francisco, he received a bachelor's degree in electrical engineering at the University of California at Berkeley. He then earned a master's degree in nuclear physics and a doctoral degree in physics at the University of Virginia. He also was a graduate of the Industrial College of the Armed Forces.

Survivors include his wife, Mavis, of Arlington; two daughters, Paula, of Mount Rainier, and Jill Kupper of New Orleans, and a sister, Babette Andrews of San Anselmo, Calif.

The family suggests that expressions of sympathy be in the form of contributions to the Signal Corps Museum Association at Fort Gordon, Ga., in memory of Col. Waterman.
