| Authors of GNU Bison. | |
| Bison was written primarily by Robert Corbett. | |
| Richard Stallman made it Yacc-compatible. | |
| Wilfred Hansen of Carnegie Mellon University added multicharacter | |
| string literals and other features (Bison 1.25, 1995). | |
| Akim Demaille rewrote the parser in Bison, and changed the back end to | |
| use M4 (1.50, 2002). | |
| Paul Hilfinger added GLR support (Bison 1.50, 2002). | |
| Joel E. Denny contributed canonical-LR support, and invented and added | |
| IELR and LAC (Lookahead Correction) support (Bison 2.5, 2011). | |
| Paolo Bonzini contributed Java support (Bison 2.4, 2008). | |
| Alex Rozenman added named reference support (Bison 2.5, 2011). | |

| and nasty bugs. | |
