Dr. Philip J. Bean, 90, a physician who practiced in St. Mary's County, Md. for 66 years before retiring last year, died of congestive heart failure Thursday at St. Mary's Hospital in Leonardtown, Md. He lived in Great Mills, Md.

Dr. Bean, who was born in Baltimore, graduated from the University of Maryland Medical School and began his practice in 1914.

A story in The Washington Post in 1959, when Dr. Bean was named the first St. Mary's County "man of the year" by the Lexington Park (Md.) Chamber of Commerce, reported that he had delivered more than 3,000 babies. By 1973, when he stopped attending births, the number had risen to nearly 5,000.

The story said Dr. Bean worked an average of 18 hours a day, including night calls, seven days a week, without taking a vacation, until an operation in 1957 slowed him down to around 14 hours a day. It reported that he had kept his fees about the same: $1 for an office visit and $25 to deliver a baby.

Also in 1959, Dr. Bean was named a Knight of St. Gregory by Pope John XXIII "for his long and outstanding service to impoverished patients, both white and black." In 1979, he was named "citizen of the year" by the Maryland chapter of the Knights of Columbus.

Survivors include his wife of 66 years, the former Sarah Goodrich, and a son, W. Calvert, both of Great Mills; two other sons, B. Eugene, of Dover, Del., and Richard A., of Lexington Park, Md., 16 grandchildren, and 24 great-grandchildren.
