Eventide was founded by recording engineer Stephen Katz, inventor Richard Factor, and businessman/patent attorney Orville Greene. The business was founded in the basement of the Sound Exchange, a recording studio located at 265 West 54th Street in New York City and owned by Greene. When Katz needed to rewind the analog tape back to a specific point on their Ampex MM1000 multitrack recorder, but limited space in the studio did not allow for a tape op (a person who would operate the tape recorder on behalf of the sound engineer), Katz asked Factor to build a gadget that would do the job, and the resulting device turned into an Original equipment manufacturer (OEM) success for Ampex. Other early products included a two-second delay for telephone research and an electrostatic deflector for dispensing nanoliter quantities of chemical reagents. Eventide’s original product line consisted of two products: the Instant Phaser (the result of an AES Show appearance), and what would become the 1745 Digital Delay Line (the result of a significant order from Maryland Public Broadcasting). Beginning with the 1745M, Eventide began widely using Random-access memory (RAM) chips in many of their products. After purchasing a Hewlett-Packard computer for researching reverb algorithms and needing to upgrade the memory in order for the computer to handle the necessary complex computations, Eventide designers realized that they could manufacture computer memory expansion far more affordably than the current market price. Therefore, Eventide began to manufacture and sell HP-compatible RAM expansion boards and did so from the late 1970s to the mid-1990s. (Wikipedia Source)
