Stephen Curtis Johnson (b. 1944; known as Steve Johnson) is a computer scientist who worked at Bell Labs and AT&T for nearly 20 years. He is best known for Yacc, Lint, spell, and the Portable C Compiler, which contributed to the spread of Unix and C. He has also contributed to fields as diverse as computer music, psychometrics and VLSI design. Johnson's passion for computing started at age five, when his grandfather took him along to his work at the Bureau of Standards. The computer he saw ("the size of a small house") made a strong impression on him, and he decided he "wanted to work with computers, and never looked back after". More information...
