Henry Laurence Gantt
(1861-1919) was a mechanical engineer, management
consultant and industry advisor.
He developed Gantt charts in the second decade of the
20th century as a visual tool to show scheduled and
actual progress of projects.
Accepted as a common-place project management tool
today, it was quite a radical concept and an
innovation of world-wide importance in the 1920s.
Gantt charts were first used on large construction
projects like the Hoover Dam, started in 1931 and the
interstate highway network which started in 1956.
