Jonathan Sachs (born in 1947) was the programmer who co-founded Lotus Development Corporation with Mitch Kapor in 1982 and created the first version of the Lotus 1-2-3 spreadsheet program. Sachs left Lotus in 1985 and now develops photo-editing software for his own Cambridge, Massachusetts based company, Digital Light & Color, which has been distributing its product, Picture Window, since 1994.
Sachs has also worked at MIT where he wrote the infuential STOIC language,[citation needed] and also at Data General.
1-2-3 was notable for its speed and efficiency. The original program was implemented in the assembly language of the PC (Intel 8088), as opposed to a higher level language such as C. It was also nearly bug-free, and introduced the letter hierarchical menus still used in Windows applications. Later versions of 1-2-3 would be implemented in C and were much larger and more complex.
