Founded in 1911 as the Computing-Tabulating-Recording Company (C-T-R), International Business Machines Corp. (IBM) can be traced back to the 1880s, when Dr. Alexander Dey invented the first dial recorder. Dey’s business later became one of the core foundations of C-T-R, along with Harlow Bundy’s Bundy Manufacturing Company, which produced the world’s first employee time clock.
