- Ielfield, Fred C., 1864-1948 (Person)
Fred Charles Ielfield (1864-1948) was a mechanical engineer and inventor. He was born in Germany in 1864 and emigrated to the United States with other family members around 1870, settling in Silver Creek, Chautauqua County, New York.
While Ielfield also patented agricultural machinery, he found success with one of the first successful machines for the automated canceling and postmarking of the mail. He and his brother, August (1869-1952), founded the Columbia Postal Supply Company in 1898 and incorporated it in 1900. Fred left the firm in 1915, after general manager John W. Slack gained control, and established the rival Standard Mail Marking Machine Company. August made improvements to his brother's invention and eventually regained control.
He married Mary L. Wackerly (1867-1944) in 1885 and the couple had a daughter, Esther. Ielfield died in 1948 and is buried in the family plot in Greenwood Cemetery in Silver Creek.
