New biography pays homage to unsung giant of Modern Industry.

The first comprehensive biography of one of America’s greatest unsung inventors of the early 20th century. As one of the original founders of the modern bearing industry, Lewis Heim was a prolific inventor of many types of precision-made bearings and machinery that ushered in the mass-production technologies of the modern industrial age. As the inventor of the Centerless Cylindrical Grinder, a significant advancement in machine tool technology, and the Spherical Rod End Bearing, that was installed in nearly every American warplane by the end of WWII, this biography provides the true stories behind their creation. Lewis R. Heim: Mechanical Genius of Modern Industry (ISBN 9780997790726), is available now in paperback ($27.50) from The Connecticut Press or your favorite bookstore.
