Converted to HTML5 7 February 2019. The world’s most powerful computer at Columbia University’s Watson Lab, 612 West 115th Street NYC, 5th floor rear, 1954. Recent Developments Eleanor Krawitz Kolchin passed away 25 January 2019. Beginning in 2017, some pages at this site have been translated into other languages. It does not aspire to be a general history or museum of computing, but in some ways it’s not far from one either.
The story of computing at Columbia is presented chronologically. Most links are to local documents, and therefore will work as long as all the files accompanying this document are kept together. There are also a few relatively unimportant external links, which are bound to go bad sooner or later — such is the Web. 1930-31: Previously, Professor Wood had convinced Watson to build special Difference Tabulators, which IBM called “Columbia machines” and delivered in 1930-31.
These machines could process 150 cards per minute and were unique in their ability to rapidly accumulate sums of products or squares . So how much did we charge? Lemmon, a Columbia University Electrical Engineering graduate and president of the Radio Industries Corporation, demonstrated the first working Radiotype machine, an electric typewriter coupled with radio transmitting and receiving apparatus. Watson’s contacts at Columbia put him in touch with Lemmon and IBM hired him. Some possibiliies of the machines can be gained from the program now in progress.
