Herman Hollerith's Type 001 Mechanical Card Punch, patented in 1901, was the first key punch; that is, the first card punch operated from a keyboard, so that the operator could punch digits 0-9, without knowing the corresponding card codes. Of this device, Hollerith said "My invention ... comprises a traveling carrier for the card, a series of key-operated punches arranged at right angles to the path in which the carrier moves, so that in any position of the card either the cypher or any of the nine digits may be punched by the operation of the proper key. The punch was patented by Herman Hollerith on the 10th September 1901 - see picture. Our example is probably from the 1930s and bears the machine number 1/7/6335 and was very kindly donated by Pam D'Arcy from Birmingham.
