Death
John H. Manny died in 1856 of a stomach illness and the manufacturing of his machine was then carried on by the Talcott brothers and Ralph Emerson until 1860, when Mr. Emerson bought out his partners and associated himself with William A. Talcott. Following the death of Manny the firm was known as Talcott, Emerson, & Co. [failed verification]
After Manny's death on January 31, 1856, McCormick appealed the case to the United States Supreme Court. McCormick lost again.
The firm meanwhile had continued to manufacture reapers as Talcott, Emerson & Company. In 1860 Emerson bought out the other partners, and then the name was changed back to Talcott, Emerson & Company about 1874.
Emerson (who was a cousin of the poet Ralph Waldo Emerson) ran the company until it became Emerson-Brantingham in 1909 under the leadership of Charles S. Brantingham. The company purchased a number of other manufacturers including Reeves & Co, but by 1915 ran into financial difficulties. After a merger with the former D. M. Osborne company, in 1928 it was bought by J. I. Case Company, now Case Corporation.
Manny's widow married Robert Hall Tinker in 1870 and lived in the house now called Tinker Swiss Cottage.
John Henry Manny is sometimes confused with John Pels Manny, a cousin.
