V. Rock Grundman, 80, a retired attorney with the Civil Aeronautics Board who specialized in airline route allocations, died Oct. 19 at Mt. Vernon Hospital in Alexandria. He had pneumonia and had been hospitalized with a broken hip.

Mr. Grundman was born in Chicago. He graduated from Dartmouth College, where he was on the football team, and then earned a degree at the Harvard Law School. He was an assistant general counsel of the Morton Salt Co. in Chicago and later was in a private law practice in Cody, Wyo.

In 1940, he moved to the Washington area and went to work in the wartime Office of Foreign Assets Control in the Treasury Department. About a year later, he joined the CAB and remained there until his retirement in 1965. One of his last cases before his retirement resulted in the establishment of an airport to serve both Fort Worth and dallas.

Mr. Grundman was a member of the Belle Haven Country Club in Alexandria and was an enthusiastic golfer there.

Survivors include his wife, Lucy Gale Grundman, of the home in Falls Church; two sons, V. Rock Grundman Jr., of Dallas and J. C. Nichois Grundman, of Atlanta, and a niece whom he raised, Gloria Smith, of Alexandria.
