MILLER, Ezra, inventor, born in New Jersey, 12 Nay, 1812. He received a good education and became a civil engineer, which profession he followed during many years in New York. In 1842 he moved to Wisconsin and settled in Magnolia, where he was soon elected justice of peace for two terms. In 1852 he was chosen a state senator and served for one term, refusing a renomination. The frequent accidents on railway trains by collision led to an endeavor to devise means for their prevention, and he finally invented his trussed platforms, compression buffers, and automatic couplers. These he patented in 1864, and they have since become almost universally adopted by the railway companies in the United States. He also obtained patents for his platform in Europe, and it is now extensively used on the continent and elsewhere. Mr. Miller has also invented other devices that have come into constant use. He has also been active in the militia. In 1833 he enlisted in a company of horse artillery belonging to the 2d New York regiment, and advanced until he reached the colonelcy in 1842. In 1851 he was appointed colonel of the 8th Wisconsin militia, which office he held during his residence in that state. He subsequently settled in Brooklyn.
