Photoshop founders Thomas and John Knoll
Photoshop got its start in 1987 when Thomas Knoll wrote software that could display grayscale images--those with a range of gray tones--on monitors that could show only black or white pixels. He and his brother, John Knoll, licensed the software to Barneyscan in 1988, then to Adobe in 1989. Adobe Photoshop 1.0 arrived in 1990, and in 1995, Adobe acquired Photoshop outright from the Knoll brothers.
