June 25, 1994|By From Staff Reports

Dr. MacCallum Rienhoff, a Baltimore native, physician and conservationist who was in the real estate business in Colorado, died May 7 of complications of cancer. He was 61.

Dr. Rienhoff moved to Denver in 1967 to complete a residency in pathology at the University of Colorado.

For the past 25 years, he was a real estate broker and partner in the Ouray Ranch and Anglers Club, the community where he lived at the headwaters of the Colorado River in the Rocky Mountains.

As a conservationist, he was interested in balancing the needs of nature and of those who live in it. He and his partner restored part of the Colorado River running through their 600-acre property.

Dr. Rienhoff attended Baltimore's Gilman School and graduated in 1953 from Yale, where he wrote his history thesis on vigilante law in San Francisco before the Gold Rush.

He was on the football and wrestling teams at Yale.

After graduating from the Johns Hopkins School of Medicine in 1957, he served an internship at Hopkins Hospital and did research on DNA as a post doctoral laboratory student of Dr. Maurice Bessman at the McCollum Pratt Institute on the Homewood campus.

Dr. Rienhoff was attracted to the arts and crafts of the Southwestern Indians as well as the art and history of the West. His hobbies included fishing and cooking. His interest in the outdoors dated to outings on the Chesapeake Bay with his brothers and his father, the late Dr. William F. Rienhoff.

He was a member of the Maryland Club, the Elkridge Club, the University Club of Denver, Trout Unlimited and the Rolling Rock Club of Pennsylvania. He was a former president of the Denver Chapter of Ducks Unlimited and on the board of the Boys Club of Denver.

He is survived by his wife, the former Joanne Winkenwerder; three brothers, Dr. William F. Rienhoff III, Hugh Young Rienhoff and Francis Colton Rienhoff, all of Baltimore; and many nieces and nephews.

A memorial service was held June 18 at Ouray Ranch.

The family suggested contributions to the Biology Department at the Johns Hopkins University, School of Arts and Sciences, for the laboratory of Dr. Maurice Bessman.
