Born in Pittsfield, Mass., and raised on Staten Island, N.Y., he earned a degree in biology and chemistry from Davis & Elkins College in Elkins, W.Va. He also belonged to the Tau Kappa Epsilon fraternity. He was a 1957 graduate of the Georgetown University School of Medicine. While at Georgetown he met his future wife, Joan McCarron.
He was commissioned an officer in the Army in 1956 and served in the medical corps. He completed his pediatric residency at what was then Walter Reed Army Medical Center in Washington, and was chief of pediatrics at the Kimbrough Army Hospital in Fort Meade. He left military service in 1962 as a captain.
In 1962, he and his wife moved to Severna Park, where Dr. Robinson established a pediatrics practice.
"He treated three generations of children in the same families," said his son, Michael W. Robinson Sr. of Reisterstown, a Baltimore County Fire Department division chief. With other pediatricians, he founded Severna Park Pediatric Associates as well as the Chesapeake Sports Medicine Center in Severna Park. Dr. Robinson retired in 2004.
He served as president of the medical staff of the Anne Arundel Medical Center, was president of the Anne Arundel County Medical Society, and chief of pediatrics at North Arundel Hospital. He was an associate professor of pediatric medicine at the University of Maryland School of Medicine and was active with MedChi, the Maryland State Medical Society. He was a fellow of the American Academy of Pediatrics and the American College of Sports Medicine.
Dr. Robinson was the athletics physician for Severna Park High School for more than 40 years.
"His dedication to medicine united with his love of sports," his son said. "He could be found every fall weekend on the football sideline for both home and away games. He was a major contributor to the effort to secure outdoor stadium lighting for the school in the 1970s."
The school's annual scholar-athlete award is named in his honor. He was inducted into the Severna Park High School Athletics Hall of Fame in 2003.
He also served on the board of the Greater Severna Park Athletic Association for several years and was the organization's secretary and vice president. He also served on the boards for the Anne Arundel County Red Cross and the American Cancer Society.
He was a confirmed Washington Redskins fan and was a season ticket holder for many years. He traveled to Minneapolis in 1992 to see the Redskins defeat the Buffalo Bills in Super Bowl XXVI.
An avid golfer, he was a longtime member of the Chartwell Golf and Country Club, where he also served as the vice president and held board positions. Dr. Robinson also served several terms on the board of trustees of Davis & Elkins College.
Dr. Robinson enjoyed spending time with his family, including his grandchildren. He vacationed at Ocean City.
"He is remembered not only for his professional expertise as Dr. Robinson but also for the incredible love, generosity and kindness with which he treated everyone he encountered," his son said.
A Mass was offered Saturday at Holy Family Catholic Church in Davidsonville.
In addition to his son, survivors include his wife of 55 years, two daughters, Deborah L. Minneman and Christina E. Davis, both of Minneapolis; a sister, Natalie Krauss of Oneonta, N.Y.; and nine grandchildren.
