Floretta A. Weiss

Floretta (Flo) Adler Weiss (January 10, 1929 – December 23, 2025) was described throughout her life as “the nicest person”. Cherished for her kindness, sharp wit and hosting prowess, she was passionate about opera and symphony and served for decades on the women’s boards of Louis A. Weiss Memorial Hospital, the Lyric Opera and Ravinia Festival.

Flo’s greatest passion, though, was her beloved husband Robert George Weiss. The two began dating when they were 16 and have remained deeply in love and dedicated to one another. This past February they celebrated 75 years of marriage amidst their children and grandchildren and their spouses and great grandchildren.

Flo is survived by her husband Robert, children Louis Arthur (“Skip”) Weiss and his wife Kathleen Aharoni, the late John David Weiss and his wife Janis, Robert Alan Weiss and his wife Ofra; grandchildren Benjamin Weiss and his husband Yoni Gorfinkel, Nicholas Weiss and his wife Juliana Piza Caballero, Jacob Weiss and his wife Jessica Druxman, Sarah Weiss and her wife Rachel Sietz, Charlotte Weiss, Loren Weiss, Evan Weiss and his wife Katherine Warther, Richard Weiss and his wife Anna Voutyras, and the late Meryl Suzanne Weiss. Flo leaves eight precious great grandchildren and many beloved nieces and nephews.

A lifelong resident of Chicago and Glencoe, IL, Flo was the youngest child of master furrier David Adler and Jane DeVere Adler who together in 1913 emigrated to Chicago from Ukraine.

A funeral for Flo will take place on Friday, December 26th, at noon, at The Mausoleum at Memorial Park Cemetery, Skokie.

In lieu of flowers, donations are invited to the Women’s Board of The Lyric Opera.
