This book details explicitly with the author's experiences with the earliest motor cars, from 1893-1901. Hiram's first invention involves mounting a gasoline engine of his own design on an old tandem tricycle. It doesn't work well but gets him a job with the Pope Manufacturing company, bicycle manufacturer. Ultimately he leads them to build both gasoline and electric vehicles with great success.

Hiram Percy Maxim was born on September 2, 1869 in Brooklyn, N. Y. He was the only son and eldest of three children of Hiram Stevens Maxim and Louisa Jane (Budden) Maxim and a nephew of Hudson Maxim. Both his father and his uncle were inventors, his father later developing the famous Maxim gun.
Young Hiram Percy graduated from the Massachusetts Institute of Technology in 1886 at the age of sixteen, the youngest member of his class.
During the next four years he was in the service of various companies manufacturing electrical equipment. From 1890 to 1895 he was superintendent of the American Projectile Company's plant at Lynn, Massachussets In 1892, while bicycling back to Lynn from a visit to Salem, Maxim was struck by the possibilities of a "mechanical road vehicle, " and by 1895 he had succeeded in building a workable gasoline-powered tricycle. He was promptly hired by the Pope Manufacturing Company of Hartford, Connecticut, then maker of Columbia bicycles, to head a new motor-carriage department. There, in addition to carrying on the development of gasoline-powered vehicles he was one of the early pioneers in this field he also designed the Columbia electric motor carriage, one of the first of its kind, which was put on the market in 1897. By 1901 the Pope Company, under Maxim's direction, had developed a complete line of motor vehicles; he remained with it and its successor, the Electric Vehicle Company, until 1907. Maxim's efforts to get a foothold in the gasoline automobile field led to his most famous invention. While devising a muffler for the gas exhaust in automobiles, he discovered the principle of the "silencer, " which, when applied to gunfire, eliminated ninety to ninety-seven per cent of the noise. It created a sensation. Editors spoke of the device as terrifying in its possibilities. Innumerable murder mystery stories were founded on it, most of the writers wrongly assuming that it could be attached to a pistol; actually it could be used only on a sealed-breech rifle. Nevertheless, the possibility of its use by criminals or persons with murderous intent caused the silencer to be denounced as a menace to public safety. Many states prohibited its sale or use; in New York possession of it was made a felony, and several foreign countries soon moved to bar its importation. Maxim had formed a company in 1908 to manufacture this and other inventions, and in 1930 he announced that he had ceased to manufacture the silencer, though there were then already 2, 500 in private hands in the United States alone. He adapted the principle, however, to many other uses to the reducing of exhaust sounds from Diesel, gasoline, and steam engines, to safety valves, air compressors, and blowers, and even an attempt to muffle street noises entering through windows. Maxim was noted as a patron of scientific amateurs, whose encouragement he considered important for the material progress of the nation. He was an organizer and for many years president of the Amateur Cinema League. He also headed the International Amateur Radio Union and the Amateur Radio Relay League, associations of amateur radio operators, and obtained official recognition for the "hams, " as they were called, when the federal government took over the assignment of broadcasting wave-lengths in 1922. When the amateurs were restricted to wave-lengths of 200 meters or less, he encouraged them in developing short waves, himself assisting in the process and opening up the field for ultra-short waves, down to ten meters. The amateurs' rights were written into an international treaty at a conference in Washington in 1927. Maxim continued as head of the Maxim Company at Hartford, Connecticut, manufacturing electrical devices and airplane parts, until his death. He held a lieutenant commander's commission in the United States Naval Reserve and was a member of a number of scientific clubs and societies. He wrote Life's Place in the Cosmos (1933); A Genius in the Family (1936), sketches of his humorous and eccentric father; and Horseless Carriage Days (1937), an account of his early automobile experiences. While on a western trip, he was taken from a train to a hospital at La Junta, Colorado, with a throat infection and died there. He was buried at Hagerstown, Maryland.
Hiram Percy Maxim was the Father of organized amateur (HAM) radio. In 1914 he organized and launched the American Radio Relay League. His amateur radio call-sign was W1AW. He was also the inventor of the Maxim silencer which was the first mass produced firearms silencer, the automobile muffler, and was a pioneer in air compressor technology.
