The history of a Gantt chart

The Gantt chart history has its own important milestones and interesting dates.

The “Gantt” in this expression stands for the last name of its creator – Henry Gantt, an American mechanical engineer, and management consultant. He designed a diagram and further published articles about his invention in 1910 and 1915. At that time, those charts were completely novel.

Surprisingly, but a diagram itself was introduced even earlier, in 1896, by Karol Adamiecki, a Polish economist, engineer, and management researcher. However, he only managed to publish his first work in 1909. Later on, in 1931, he published a more widely known article where he described the harmonogram – he called the chart like this.

The reason why the Gantt chart is named after the American engineer and not the Polish one is quite obvious. Henry Gantt spoke and wrote in English, while Karol Adamiecki published his articles in Polish and Russian.
