February 19th marked the 20th anniversary of the amazing photo-editing software Adobe Photoshop. Let me put that another way: a version of Photoshop premiered on 2/19/1989. I didn't think computers in the late-80's were even capable of displaying "photos"!
Appropriately, I used Photoshop to make this picture of the icon revolution. :)
Like a lot of cool inventions, Photoshop was developed at the University of Michigan by brothers named Thomas and John Knoll. Their father, Glenn Knoll, a professor at U of M, taught his sons an appreciation for both photography and computers. In 1987, PhD candidate Thomas began working on a computer program on his Apple Macintosh Plus to display grayscale images (since previously images were only in black and white pixels)... and the rest is history!
