Sewell's Erector Set Heart Pump
An artificial heart for less than $25
While studying medicine at Yale University in 1950, William Sewell, Jr. and William W.L. Glenn invented this artificial heart, which they successfully used in experimental bypass surgery on dogs. They made the prototype out of materials such as glass tubing, valves bought at the dime store, a child's Erector Set motor, and tanks of compressed air and vacuum pumps that were part of routine laboratory equipment. Total cost: $24.80.
||Acquired in 1959 from Sewell's mother, Lucile S. Sewell
