Later life and death

During the last four years of his life, McCormick became an invalid, after a stroke paralyzed his legs; he was unable to walk during his final two years. He died at home in Chicago on May 13, 1884. He was buried in Graceland Cemetery. He was survived by his widow, Nettie, who continued his Christian and charitable activities, within the United States and abroad, between 1890 and her death in 1923, donating $8 million (over $160 million in modern equivalents) to hospitals, disaster and relief agencies, churches, youth activities and educational institutions, and becoming the leading benefactress of Presbyterian Church activities in that era.

Official leadership of the company passed to his eldest son Cyrus Hall McCormick Jr., but his grandson Cyrus McCormick III ran the company. Four years later, the company's labor practices (paying workers $9 per week) led to the Haymarket riots. Ultimately Cyrus Jr. teamed with J.P. Morgan to create the International Harvester Corporation in 1902. After Cyrus Hall McCormick Jr., Harold Fowler McCormick ran International Harvester. Various members of the McCormick family continued involvement with the corporation until Brooks McCormick, who died in 2006.
