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 cell]]s, thereby reducing the incidence of [[transfusion reaction]]s and [[virus|viral]] infections.

Pall expanded the business, adding additional products. Today, Pall Corporation has sales in excess of $2.0 Billion.
