Edward John O'Connell M.D., 83, of Rochester completed his life plan peacefully at his home surrounded by his family on Monday, December 11, 2017.

Ed was born in Rochester on May 30, 1934 to Celia O'Connell (Schwartz) and Edward O'Connell. He graduated from Rochester High School in 1952 and University of St. Thomas in 1956. In 1960, he graduated from St. Louis University School of Medicine.

He married Maureen Gallagher, on June 7, 1958 in Grand Forks, ND. They moved to St. Louis, MO during his medical school before making their home in Rochester. From 1961-1965, he did his pediatric residency at the Mayo Clinic. In 1965, he was appointed to the Mayo Clinic staff in the Department of Pediatrics and Allergy/Immunology. In 1966, he was drafted to United States Air Force and retired from service with the rank of Captain in 1969. He returned to the Mayo Clinic where he was a professor of Pediatrics, Allergy/Immunology and Mayo Clinic College of Medicine, president of the American Association of Certified Allergists, president of the American College of Allergy, Asthma and Immunology, and president of the Irish and American Pediatric Society. He received  the following awards: "Teacher of the Year" Hall of Fame in 1987, "Distinguished Mayo Clinician" award in 1995, "Gold Headed Cane" award from the American College of Allergy, Asthma and Immunology in 2003, and the "Distinguished Service Award" in 2005 from the American College of Allergy, Asthma and Immunology.

In his retirement, Ed "went back to school again" and was the editor-in-chief of the Annals of Allergy Asthma and Immunology medical journal. He loved his family first and also enjoyed nature, music, fishing, teaching, dogs, traveling and especially woodworking, making toys for children that he donated to the Rochester Ronald McDonald House.  He loved to make people laugh; his unique perspective, stories, brilliant mind and sense of humor kept everyone on their toes.  A true gentleman who was full of love, compassion and faith.

Ed is survived by the love of his life, Maureen "Rene"; three children, Maureen (James) Lehman of Minneapolis, Sheila (Peter) Roth of Coto de Caza, CA, and Edward (Hadley) O'Connell III of Mazeppa, MN; eight grandchildren; and one great-grandchild. He is preceded in death by two daughters, Kathleen (Mark) Krebsbach and Colleen O'Connell.
