From the New York Times obituary:
A courtly man whose gentle demeanor masked an intense perfectionism, Mr. Penn adopted the pose of a humble craftsman while helping to shape a field known for putting on airs. Although schooled in painting and design, he chose to define himself as a photographer, scraping his early canvases of paint so that they might serve a more useful life as backdrops to his pictures.
He was also a refined conversationalist and a devoted husband and friend. His marriage to Lisa Fonssagrives, a beautiful model, artist and his sometime collaborator, lasted 42 years, ending with her death at the age of 80 in 1992. Mr. Penn’s photographs of Ms. Fonssagrives not only captured a slim woman of lofty sophistication and radiant good health; they also set the esthetic standard for the elegant fashion photography of the 1940s and ’50s.
Ms. Fonssagrives became a sculptor after her modeling career ended. In 1994, Mr. Penn and their son, Tom, a metal designer, arranged the printing of a book that reproduced his wife’s sculpture, prints and drawings. In addition to his son, Mr. Penn is survived by his stepdaughter, Mia Fonssagrives.Solow (who renders her name with a dot), a sculptor and jewelry designer; his younger brother, Arthur, the well-known director of such films as “Bonnie and Clyde,” and nine grandchildren.
