Who Was Alexander Langsdorf?
Before examining the book, it is vital to understand the author. Alexander S. Langsdorf (1877–1973) was not merely a textbook writer; he was a giant of early electrical engineering education. A long-time professor at Washington University in St. Louis, Langsdorf possessed a unique ability to bridge the chasm between purely theoretical physics and the practical, gritty reality of rotating machinery.
