During the early 1930s Mr. Hans Rudolph designed and built what were possibly the first Respiratory Valves specifically for use in Pulmonary Function Studies with humans and animals. In 1960 Hans and John Rudolph formed and incorporated Hans Rudolph, inc. as it continues to exist today. Additional family members continue to join the company, which strengthens its future growth and existence. We currently have the second, third & fourth generations of Rudolphs working together with pride to continue providing the old world craftsmanship and quality service to the high technology world of today.
