GRASS GIS Birthday
29 July 1983
The first user manual for (what would become) GRASS GIS titled “GIS Version 1 Reference Manual” was published by J. Westervelt and M. O’Shea, on 29 July 1983. Jim Westervelt began work on what would become GRASS GIS earlier through his master's thesis, but the publishing date of the first user manual is the celebrated birth date of GRASS.
