Born in 1914 in Thunder Bay, Ontario of Russian immigrant parents, he grew up on a farm in Saskatchewan. He attended McGill University, from which he was granted a bachelor's degree in chemistry and a Ph.D. in physical chemistry.
In 1946, he established Pall Corporation. The company's initial focus was on the development of filters for use in aircraft hydraulics. However, in 1959, when Dr. Pall's first wife, Josephine, died of aplastic anemia, he began to work on the Pall filter. Mrs. Pall had undergone multiple blood transfusions in the course of an illness, which were ultimately unsuccessful. His Pall filter was designed to make blood transfusions significantly safer by filtering out white blood cells, thereby reducing the incidence of transfusion reactions and viral infections.
Pall expanded the business, adding additional products. Today, Pall Corporation has sales in excess of $2.0 Billion.
Pall was a trustee of the North Shore University Hospital.
