Newby died Dec. 17, 2020, one day after his 92nd birthday.
He was raised in the Chestnut Hill area of Philadelphia, attended Chestnut Hill Academy, and graduated from St. Mark’s School. At Princeton he was a member of Cottage Club, majored in politics, played freshman ice hockey, and joined the Rugby Club.
After several years in retailing and serving briefly on active duty with the Army Reserve, Newby returned to Philadelphia and started in the investment business in 1956 with a local broker. In 1960 he began a 44-year career with the Philadelphia office of Smith Barney as a retail and institutional account manager, and he continued to manage accounts with Pennsylvania Trust after his formal retirement. He was always very civic-minded and was active as an officer and board member of a variety of Philadelphia-area business and not-for-profit organizations.
An avid golfer, he and his wife, Nancy, spent their summers sailing and playing tennis at their vacation home in Beach Haven, N.J.
Newby was predeceased by Nancy in May 2020. They are survived by son William ’76; daughters Anne, Sally, and Juliana; nine grandchildren; and two great-grandchildren.
