Case File of Howard L. Ingersoll
Committee on Science and the Arts
1933 Longstreth Medal

<< Case Files Home

Case File Catalog Summary

Howard Ingersoll invented The Locomotive Booster. He was awarded the Edward Longstreth Medal in 1933 for that invention. Locomotives fitted with Boosters were able to reach full speed in shorter time than those not fitted with such. The Booster also allowed the train to start with less shock. Locomotive Boosters enabled large trains to handle mountainous terrain that otherwise would have been impassible.

In this catalog-only case file presentation, you can examine the reports of The Franklin Institute in its Committee on Science and the Arts investigation into Ingersoll and his invention. The "descriptive report" listed below is particularly revealing about the function of the Booster. You will also find an assortment of ephemeral pieces and legal exhibits from a case between Ingersoll/The Franklin Railway Supply Co., and Bethlehem Steel Company who also claimed to have invented a booster device.
