Adobe has donated the source code of the first version of photoshop. The server seems to be down due to high demand, but you can find the link and more information on http://www.computerhistory.org/atchm/adobe-photoshop-source-code/
I can´t wait to download the actual Pascal source as I was an active computer graphics programmer at that time and discussed so called convolution filter technology with the brothers Knoll, mainly John. At that time the program was still called Display.
Unfortunately Apple seems to have blocked the release of the needed app-libraries. Grady Booch, trustee of the museum and chief scientist for software engineering at IBM research has a great introduction:
“Opening the files that constituted the source code for Photoshop 1.0, I felt a bit like Howard Carter as he first breached the tomb of King Tutankhamen. What wonders awaited me?"
A treasure cove with 128,000 lines of code that made history

Ha! I didn't learn Photoshop until they first ported it to Windows, so I guess that makes me kind of a newb.
I thought the first Photoshop was written by Ben Adobe, the founder of the Adobe corporation.
Certainly not +Ivan Mashchenko they just bought it from the Knoll brothers.
Who’s Ben Adobe +Ivan Mashchenko? Adobe was founded by Chuck Geschke and John Warnock. One of their first projects was converting their research project (a resolution independent page description language) into a marketable product called Postscript. They then digitized their first typeface (Times) by hand and went on to design Adobe Illustrator.
Hahahaha. Ben Adobe was an Ad Spoof!!!!!
Here is his Twitter by the way: https://twitter.com/pilato2009
+Ivan Mashchenko No, that was not the guy in the ad spoof i remember. I don't know where or how that started, it was years ago. But i got your joke.
