Dr. Manlove was appointed a fellow in internal medicine at the Mayo Foundation for Medical Education and Research in Rochester, Minn., in 1941. He completed a master's degree in medicine in 1943 at the University of Minnesota. He then worked as a cardiologist at the Mayo Clinic through 1945.
In the late 1940s, he married Margaret Perkins. The couple had three children.
He returned to Philadelphia, where he served as an assistant professor of medicine at Temple until 1950. He also held posts at Episcopal Hospital during that period.
Dr. Manlove then worked for the American Medical Association in Chicago, serving as the associate secretary of the Council on Medical Education and Hospitals.
In the mid-1950s, he moved to Colorado, where he was dean of medicine and director of the medical center.
He returned to Philadelphia again in 1959, working as a staff physician and professor at the Temple School of Medicine and at Bryn Mawr Hospital until his retirement.
For about 30 years, Dr. Manlove kept a farm near Montrose in northeastern Pennsylvania, where he planted trees and cultivated an extensive garden.
He was an accomplished skier into his 1980s. After retiring, he enjoyed annual ski trips to Colorado with his family.
Dr. Manlove also was an avid angler, enjoying both freshwater and ocean fishing in the Philadelphia area, Minnesota, Colorado, and Vermont. "Anywhere he lived, he fished," said his daughter, Caroline Christ.
He also enjoyed baking bread, she said. "He would make eight loaves at a time and knead them on the counter."
Dr. Manlove was a raconteur, regaling his friends and relatives with stories of his life and the people he knew.
"He loved talking to people," his daughter said. "It was easy for him to strike up a conversation with anyone. He had a twinkle in his eye."
He also loved home carpentry, poetry, and classical music, attending performances of the Philadelphia Orchestra.
"He was a very warm and positive person," his daughter said.
In addition to his wife and daughter, Dr. Manlove is survived by another daughter, Elizabeth; a son, Charles; a stepson, Allan Kluber; and seven grandchildren.
A celebration of his life will be held at 3 p.m. Saturday, April 13, at Beaumont at Bryn Mawr, 77 Middle Rd.
