A Herman Hollerith early IBM tabulating machine

Standard

Today at the MIT Swapfest, I found and bought a punch card making machine/device.  It is from The Tabulating Machine Company.  The Tabulating Machine Company was founded by Herman Hollerith – initially in 1896 as Tabulating Machine Company, and again in 1905 as The Tabulating Machine Company – to commercialize his tabulating machine which he invented and revolutionized the US Census tabulation process in in the late 1800’s.  In 1911, The Tabulating Machine Company and three other companies came together as the Computing Tabulating Recording (CTR) company, which a few years later in 1924 became International Business Machines corporation (IBM).  But the individual companies in the CTR holding company continued to use their original name until 1933, so this device could have been made anytime between 1905 and 1933.
