Dr. Henry Stern (Hank) Sommers Jr., a longtime summer resident of Flanders Lane in Menemsha, died August 6 in St. Mary Hospital in Langhorne, Pa., near Pennswood Village.

Mr. Sommers had lived on Flanders Lane with his wife, Nancy. They moved to Pennswood Village in 1990. Mrs. Sommers died in 2002.

Mr. Sommers was born in St. Paul, Minn., in 1914 and grew up there and in the family’s summer home in Hudson, Wis. He received a bachelor’s degree from the University of Minnesota in 1936 and a doctorate in physics from Harvard in 1941. After working at the Massachusetts Institute of Technology from 1942 to 1945, Rutgers University from 1946 to 1949, and the Los Alamos Scientific Laboratory from 1949 to 1954, he moved to Princeton, N.J., along with Nancy and their four children, to take a job as a Fellow of the RCA David Sarnoff Research Laboratory. He held the position until his retirement in 1984.

Hank was an avid birder. Among other things, he made it an almost daily practice while on the Vineyard to put his binoculars around his neck and go out for a walk in the woods to see what birds were there.

He also loved to play tennis, usually doubles. And to read. He was a subscriber to the Vineyard Gazette right up until the time of his death.

Nancy, an antiques dealer, enjoyed going to swap meets and the annual antiques show. She and her daughter, Heather, a year-round Vineyard resident, liked going out together to sketch and paint.

Hank and Nancy Sommers are survived by four children: Ann Harrington, Heather Sommers Sussman, Craig Trenholm Sommers, and Henry Stern Sommers 3rd, as well as three grandchildren and four great-grandchildren.
