Aaron M. Fine, a founder of Fine, Kaplan and Black in Philadelphia, died Oct. 17 at the age of 90.

Fine focused on class action litigation and was a nationally recognized trial lawyer.

“His greatest legal accomplishments were arguing before the Supreme Court of the United States,” Allen D. Black of Fine Kaplan said. “I remember sitting next to him as a young lawyer in awe of him.”

Fine argued the class action case Eisen v. Carlisle & Jacquelin before the U.S. Supreme Court in which the justices held that federal trial judges should not consider the merits of a suit when deciding the issue of class certification.

Fine also wrote the brief that established the “fraud on the market” principle in securities litigation, according to a release provided by the firm.

Fine established Fine Kaplan in 1975 with Arthur M. Kaplan and Black.

Black told The Legal that people will remember Fine fondly because of “his generosity, his kindness and his wit.”

Beyond the law, Fine “loved language and having fun with language and reading,” Black said. “He was one of the most well-read people I’ve known.”

Fine knew eight languages in addition to English; collected and made his own art; and read voraciously, the release said.

Fine was born in England and became a U.S. citizen in 1944. He earned both an undergraduate and a law degree from the University of Pennsylvania, according to the release.

Fine is survived by his son, David; and his daughter, Sue; her husband, Steve Purdy; and her stepdaughter, Isabel Purdy.

A memorial reception to be held at the law firm is being planned for a later date. •
