KLIGER, Isaac E. “Itzik” of Lexington, MA, and Aventura, FL, on January 25, 2022, at the age of 87. Beloved husband of Judith (Tuzman) of 62 years. Devoted father of Ronn (Elisabeth Wolfson) of Cambridge and Tamar Schneider (Craig) of Newton. Loving grandfather of Daniel and Naomi Kliger; Sarah and Benjamin Schneider. He also leaves extended family near and far as well as many long-time friends, particularly in Israel.

Born in Lodz, Poland, to Vital and Shlomo Kliger, the family immigrated during his infancy to Eretz Israel, settling in Tel Aviv and later in Haifa. He was very proud of being the youngest member of the Irgun; at the age of 13, he served as a messenger between posts in the battle for Jaffa. While serving in the Israel Defense Forces, Itzik earned degrees in electrical engineering from The Technion (Israel Institute of Technology) before he and Judy sailed to New York. He enrolled at Brooklyn Polytech and earned a PhD in electrical engineering in 1963. While still a student, he was recruited by the U.S. Atomic Energy Commission to work at their Argonne National Laboratory in Illinois.

Later employed at Lockheed Aircraft Corp. in Huntsville, AL, he regularly sought problems to solve at NASA’s Space Flight Center nearby. Itzik was constantly doing calculations in his head and on scraps of paper if not in the air, long after he retired from Raytheon’s Missile Systems Division in Massachusetts as Consulting Engineer. He relished teaching and tutoring graduate students. With much innovative thinking and coming up with novel solutions, he proudly displayed his many patents in his home office.

As a scholar of Torah and Talmud, Judaism was an intellectual exercise for Itzik. He was particularly adept at explaining the intricacies of the Hebrew calendar because of his deep knowledge of mathematics. He regularly taught adult classes at Temple Emunah and many other venues. He especially loved teaching his grandchildren whatever was at hand: history, math, kite building or rock skipping.

He enjoyed swimming at his Lexington neighborhood pool, then on Cape Cod and in Florida. Itzik and Judy cruised frequently and traveled extensively, regaling family with stories of their adventures.

The family wishes to thank the attentive, caring staff at Belmont Manor Nursing & Rehabilitation Center, Belmont, MA.

Due to the pandemic, funeral services are private.
