David H. Cassidy ’58

David H. Cassidy ’58 passed away in West Lebanon, New Hampshire, of Parkinson’s disease on August 13, 2023. Dave grew up in White River Junction and Newport, Vermont, majored in chemistry, and later earned an M.B.A. at NYU. He was on the Dartmouth ski team all four years and was a member of Alpha Theta. Dave joined Johnson & Johnson in 1958, stayed 25 years, and eventually became VP of operations. Later he was general manager of Fisher Scientific’s chemical division and then chief operations officer of Eastern University. In June 1959 he married Corrinne Secondo and embraced her three children. Together, Dave and Corrinne led an adventurous life, hiking 1,100 miles of the Appalachian Trail one summer while in their 60s and serving as Christian missionaries several times in Moldova and Tajikistan. Dave developed Parkinson’s 12 years ago but was determined to stay as active as possible and continued to downhill and cross-country ski until four years ago. He was a regular participant in The Prouty, an annual bicycling fundraiser for the Dartmouth Cancer Center. For his 25th reunion book, Dave wrote, “I have cherished my Dartmouth experience and have been many times its beneficiary. My only regret…is that many years ago Dartmouth strayed from the Christian teaching established by Rev. Eleazar.” Corrinne predeceased him; he is survived by their daughter and son, plus her three children, including Michael Monaco ’71.
