A Customs Officer is Father of Typewriter
Christopher Latham Sholes (1819-1880) Collector of Customs during the Lincoln Administration along with his partner, Samuel Soule, patented a numbering machine in 1866. They also patented their first typewriter with another partner, Carlos Glidden in 1868.
By 1873 Sholes developed the QWERTY keyboard, still the industry standard today, to help keep typewriter keys from jamming.
