Thomas and John Knoll began development on the first version of Photoshop back in 1987. The program was intended from the start to be the premier tool for manipulating images that were digitised by using a scanner, which back in the late 80’s and early 90’s was a very rare and very expensive accessory.
Looking back version 1 of Photoshop is incredibly primitive by modern program standards, many features are missing including layers which only made an appearance in version 3.0!
The Computer History Museum aims to preserve and present for posterity key artefacts and stories of the information age. The Computer History Museum was formally established as a non-profit organization in 1999. The Museum is dedicated to the preservation and celebration of computing history.
By teaming up with Adobe the Computer History Museum has been able to secure the source code of Photoshop 1 which it has now made available free of charge just like it did with competing product MacPaint back in 2010.
