H. Jack Drucker, 71, of Montclair, died on Saturday, Aug. 11.

Mr. Drucker was born in Brooklyn, N.Y., on Oct. 4, 1946, to Ethel and Ernst Drucker, a family of musicians. He grew up in Washington Heights and attended the Bronx High School of Science before matriculating at the City College of New York, graduating with a bachelors of science degree in mathematics. He then received his masters of math from the University of Illinois at Urbana-Champaign.

He spent his 30-year teaching career at the Packer Collegiate Institute of Brooklyn and primarily the Borough of Manhattan Community College (CUNY), where he served as deputy chair of the math department for several years.

After his retirement, he continued to tutor math students in Montclair with the community organization Succeed2gether and in private practice.

He played the flute with passion, beginning by teaching himself as a young adult. As a dedicated actor, he starred in many roles in the New York and New Jersey area. He loved to create poetry, writing inspirational poems about his love of life, even in the face of adversity.

Mr. Drucker and his wife Francesca Elms moved from Manhattan to Montclair in 1991 with their young sons. Shortly thereafter, the family joined the Unitarian Universalist Congregation at Montclair, where he chaired the Music and the Worship Committees, mentored young adults, taught religious education, and co-created a theater group, where he was responsible for the production of many plays.

He was politically active, working for gun violence prevention with Ceasefire NJ and for progressive change with BlueWaveNJ. He was one of the founding members of the Friends of the Bellevue Avenue Library, volunteering for over four years to help it re-open in austere budget-times and then to keep it open. He helped to fund raise for the library by arranging for summertime Music Mondays on the Bellevue Library Plaza and other musical events involving many community members.

Mr. Drucker is survived by his wife of 36 years, Francesca Elms, his son Michael (married to Justine McLellan), and his younger son Jonathan; both sons have been inspired by their father to create a life in the arts. Among many other family members, he is also survived by his brother Eugene Drucker, sister-in-law Roberta Cooper, and nephew Julian.

There will be a memorial service/celebration of Jack’s life on Sunday, Sept. 23, at 3 p.m. at the Unitarian Universalist Congregation at Montclair, 67 Church St. Instead of flowers, please consider honoring Jack by contributing to the Music Endowment Fund at the UU Congregation at Montclair. Arrangements were made by O’Boyle Funeral Home working with the Funeral Consumers Alliance of Northern New Jersey.
