John Miller Arnold
July 11, 2004
John Miller Arnold of Falmouth died July 11 at his home. He was 67. He was the son of the late Arthur H. and Lucile E. Arnold of St. Paul, Minnesota. Born in St. Paul, he received his bachelors and doctoral degrees in zoology from the University of Minnesota. In 1960 he began a lifetime association with the Marine Biological Laboratory in Woods Hole where he was a member of the corporation. Dr. Arnold's research explained the reproduction and embryology of the Atlantic squid, Loligo pealii. His scientific work revolved around the cell biology and natural history of squid, octopus and most recently, the chambered nautilus. In the 1960s, he was a primary discoverer of the actin ring and contractile mechanism involved in cell division. An academician, Dr. Arnold was professor of cell biology at the Pacific Biomedical Research Center of The University of Hawaii where he helped design the Kewalo Marine Laboratory. He retired to Falmouth in 1995 as a year-round resident. He leaves a daughter, Katherine Elizabeth Williams-O'Donnell of Norman, Oklahoma, and brothers William P. Arnold and Bruce H. Arnold of Roseville, Minnesota; three nieces; and a nephew. A private memorial will be held at a later date. Memorial contributions may be made to the John M. Arnold Fellowship Fund at the Marine Biological Laboratory, Woods Hole, MA 02543.
