Irving Lieblich

Born on June 8th, 1928, in Brooklyn, he went to Boys High, Brooklyn College, and Brooklyn Poly. Irving was physical chemist by training and originally applied his knowledge to inventing chemical processes for paper treatment. He obtained 9 patents for these processes and produced electrolytic paper for the first facsimile machines.

He spent most of his career working for the American Institute of Physics but in his later years he decided to become a high-school math teacher, teaching in the NYC public high school system. He loved teaching math to all kinds of students and continued to do so into his eighties.

His hobbies included playing bridge, achieving the level of lifetime master, origami, and watching sports - especially baseball.

He is survived by his wife Felicia Lieblich and two sons David and Gerald Lieblich.
