Len’s story was a New York story. He was born in 1941 in Bensonhurst, Brooklyn to Lilly and
Maurice Baum, Jewish immigrants who had fled persecution in Europe for refuge in America. Len was their second of three children; he was particularly close with his younger sister, Rosalyn, who was born with severe special needs.
Len lost his father at the age of 10, and while his sister and mother spent time navigating health issues and hospitalizations, he moved around: living with family members and in orphanages, relying on the generosity of others—and, he would be quick to point out, New York’s social safety net—for food and shelter. He promised himself that if he ever made it out of Brooklyn, he would pay their kindness forward.
Still, despite the turbulence of his upbringing, Len was an excellent student. While attending
Lafayette High School, he made enough of an impression to land a scholarship to Queens
College and then New York University, where he obtained both his Bachelor’s Degree and his
Juris Doctor. Far more importantly, while attending Lafayette High School, he made enough of an impression to land a date with Elizabeth Korman; half a decade, a dramatic pre-prom break-up, and a chance encounter in the park later, she finally agreed to marry him. They were wed at Union Temple in 1963.
After graduating from law school in 1965, Len began his career at Phillips Nizer, Benjamin, Krim & Ballon, where he was a mentee of the famed trial lawyer Louis Nizer. Widely recognized for his excellence in litigation, including complex commercial and fiduciary matters, he went on to become a partner at several major New York law firms before joining Proskauer Rose LLP, where he served as Counsel until his retirement.
Len and Elizabeth started a family, just as the two were starting their careers. Their daughter
Jennifer was born in Brooklyn in 1966, and named in the same temple where her parents were wed. Douglas followed next, and they then moved to Merrick, Long Island where they welcomed David and raised their family.
As a teen, Len found respite on the water, learning from fisherman how to catch striped bass in Sheepshead Bay and under the Whitestone Bridge. He supported his education and his family with his catchings, and by working at Capital Fishing and Tackle. By the time he was a young adult, that escape had developed into a full-blown obsession. An avid angler, he enjoyed
nothing more than wading into a rushing river, and standing there, for hours, hoping to reel in a
catch with one of his handmade flies. He occasionally convinced his children and wife to join him on the water; among his proudest moments was when Elizabeth was featured in Atlantic Salmon Journal for her ice-fishing prowess in Siberia. Over the years, Len took up a number of new hobbies: wine-collecting, photography, and hunting, to name a few. He also continued to tick countries and experiences off his bucket list: flyfishing in New Zealand, salmon fishing in Iceland, and bonefishing in Harbor Island; dodging buffalo in Yellowstone and photographing giraffes in South Africa; sightseeing in China and wine-tasting in Argentina—all with Elizabeth by
his side.
When his children were young adults, Len and Elizabeth moved to Chappaqua, New York. That
house became a hub for family life; many a Thanksgiving dinner and Passover Seder was spent at the dining room table, now filled with Jennifer, Douglas, and David’s spouses, David, Heather, and Tilly, and Len and Elizabeth’s seven grandchildren. Having been in the office during many of his own children’s milestones, he was grateful to have a second chance to experience them with his grandkids: to write stories about crime-solving potatoes with Sarah, shop in Paris with Emily and Maiya, fish and hunt with Ben, talk politics and wine with Aaron, and take long walks in the woods with Auden and Felix. He was also thrilled to have an excuse to keep the house stocked with candy; an incorrigible sweet-tooth, he was known to polish off a gallon-bag of jelly raspberries, sneak handfuls of Good & Plentys before dinner, and raid his children’s Halloween
stashes of anything nutty or licorice.
As he often told his family, he had come a long way from poverty in Brooklyn—and he made
good on his promise to help others rise above their circumstances too: donating to a number of social welfare causes, the university that afforded him an education, as well as the Multiple Myeloma Research Foundation and various Democratic candidates for office—Len “never, not once, voted for Republican,” a statement that earned him a cameo at the 2020 DNC. He will be missed for his wit and imagination, his legal mind and love of the outdoors, his remarkable resilience and sharp sense of style.
Leonard Baum is survived by his wife of 63 years, Elizabeth; his children, Dr. Jennifer Gruen
(David), Douglas Baum (Heather), and David Baum (Tilly Macalister-Smith); and his
grandchildren, Sarah, Emily, Aaron, Ben, Maiya, Auden, and Felix. He was predeceased by his
parents, siblings, and beloved Aunt, Bea Kaplan.
In lieu of flowers, please consider a donation to The Nature Conservancy—and have a handful
of jelly raspberries, a scoop of Cherry Garcia, and a glass of fine Burgundy—in Len’s honor.
