This is a book that was written by my great-great-grandfather, Harry Leigh Derby. Because his family was very poor, he started working at a young age, first as a newsboy, then as a basket maker when he was nine, and at twelve he was employed by the Afton Railroad. His experience in travel coordination allowed him to work his way up until he was hired as the Traffic Manager for the Casein Company and then the Kalbfleisch Corporation, which manufactured chemicals. He was able to leave behind a life of poverty and move to New Jersey. It was during this time that he was invited to write a volume of The Traffic Library, a textbook on the management and organization of Industrial Traffic Departments commissioned by the Advisory Traffic Council. Over the next decade his book put him in contact with many political figures who asked his advice on traffic and labor issues and he was appointed a seat on the National War Labor Board under President Roosevelt. He also travelled regularly for work and was granted a Cedula de Identidad by Argentina. At the end of World War II, following the early deaths of both of his children, he retired from business and politics to devote the time to help raise his grandchildren.
