Leah Marcus, 90, of River Forest, died on March 28, 2026. Born in February 1936 in Chicago to Betty (Bernstein) and Lou Nathanson, she was a graduate of Senn High School and the University of Wisconsin, where she co-edited the university’s award-winning newspaper with her lifelong friend, Julie Baskes.
In 1961, she and Philip Marcus married. Together they enjoyed theater, Chicago’s comedy clubs (like Gate of Horn), dining (especially Ristorante Agostino), and the Chicago Symphony Orchestra. They raised a close and loving family: Jonathan (Lorraine Applebey), Jessica (Howard Fishman), and Sarah (Jeff Fraum); grandchildren Matt Maenpaa (Zoe Streicker-Howard), Jacob Marcus, Benjamin Marcus, Sara Fraum, Zachary Fraum, and Dianarose (Sammy) Blivaiss; and great-grandchild Finn Maenpaa.
Leah was publicly engaged even as a teen and throughout her life, including serving as a page at the 1952 Democratic National Convention. After college, she embarked on a career of journalism and public service, writing for several trade publications and the Chicago Sun-Times. In the 1980s, she served as an elected member and ultimately president of the Oak Park and River Forest High School District 200 Board of Education. In that leadership role, she earned widespread respect for her intellect, care, and exceptional abilities to listen, ask questions, understand, communicate, and empathize.
Leah is survived by her brother-in-law, Charles Marcus (Maureen Vollen); her children, grandchildren, and great-grandchild; by many cousins, nieces and nephews and their families; and by many dear and devoted friends.
In lieu of flowers, contributions to Oak Park Temple, Magen David Adom, and Planned Parenthood would be appreciated.
