Meeting regarding the formation of the Computing- Tabulating- Recording Company (C-T-R)
The first decade of the 20th century was marked by a number business launches and consolidations, all of which eventually led to the formation of the Computing- Tabulating- Recording Company (C-T-R) - IBM's predecessor - in 1911.


Factory in Endicott, New York
For example, the International Time Recording Company (ITR) was formed in 1900 and the Computing Scale Company of America was incorporated in 1901 - and these two businesses were two of the three chief components of C-T-R a decade later. ITR itself acquired other companies, such as the Dey Time Register Company, during this period, broadening the time recording equipment product line.

In addition, ITR outgrew its original manufacturing facilities, and built a modern factory in Endicott, New York, on the site of what later became an IBM Plant No. 1.
