The Geo D. Whitcomb Company was founded by George Dexter Whitcomb (1834–1914), of Chicago, Illinois, who started a modest machine shop in 1878, and began the manufacture of coal mining machinery, laying the foundation for the concern that became known as The Whitcomb Locomotive Company. ==Beginnings== Early in life, George Dexter Whitcomb, moved with his family, from Brandon, VT, to Kent, OH. Here he started his business career, engaging with the Pan-Handle Railroad, as purchasing agent. While in this employment, the air brake was invented, and he became very interested in its development. He co-operated in making the tests of the Westinghouse Air Brake and was one of the original stockholders and members of the Board of Directors of the Westinghouse Air Brake Company, when it was organized. In 1868, George and his wife Leadora had a son, William Card Whitcomb. As an adult, William received an engineering degree from the newly founded, University of Southern California in 1889. Upon graduation he would join to assist and improve his father's business. George left the Pan-Handle Railroad about 1870, moving to Chicago, where he took charge as manager of the Wilmington Coal Mining and Manufacturing Company's mines at Braidwood, IL. He also managed the Wilmington Coal Association which handled the output of the Braidwood, IL coal field. He continued in charge of these mines until about 1878. While there, the Harrison Mining Machine was brought to his attention. The concept of the power pick was that of a hand-held machine controlled by one person and operated by compressed air. He saw merit in the idea and took hold of the machine. He developed and perfected it into what is now known as the “Puncher Machine.” This machine was the first successful undercutting machine put on the market in this country. He resigned his position with the coal company about 1878 to devote his entire time and attention to the mining machine business. In 1896, his firm, then located at Orleans and Ohio Streets in Chicago, Illinois and was incorporated under the laws of Illinois as the George D. Whitcomb Company.〔The Black Diamond, Vol. 52, No. 26, June 27, 1914, p. 551 http://books.google.com/books?id=GelZAAAAYAAJ&pg=PA551&dq=whitcomb+panhandle+railroad&hl=en&sa=X&ei=iQajUI3fM6K_yQHFroG4Bw&sqi=2&ved=0CDYQ6AEwAw#v=onepage&q=whitcomb%20panhandle%20railroad&f=false〕 In 1884, he ultimately relocated to California, on account of his wife, Leadora's health. Here he purchased a tract of land and built a home. This industrialist, inventor and family man then developed and founded a suburb of Los Angeles, CA, Glendora, California. He settled his family and spent the rest of his life at this place. About 1900, William Card Whitcomb became Vice President of the company and soon hired William Frederick Eckert as an engineer. During this time the company was producing knitting machinery and pneumatic mining equipment. In 1907, George D. Whitcomb resigned as an officer of his company, leaving William Whitcomb the president and majority stock owner. Mules and man power had long been used exclusively as the motive power in moving coal from the mines, but this method was expensive and unsatisfactory. Because of the insistent demand for a more economical method, experiments were being conducted using for power— electricity, compressed air and rope drive. Gasoline engines were definitely a novelty in those early days, nevertheless William Whitcomb, together with Eckert, decided the principle could be successfully applied to a small mine locomotive. In April, 1906 the first successful gasoline locomotive was built and installed in a large Central Illinois coal mine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Geo D.
