Who invented Har-Tru tennis courts?
Henry Alexander Robinson
In 1931, a contractor named Henry Alexander Robinson (HAR) engineered a new clay court surface using American stone first mined in Pennsylvania. The surface had a true (TRU) green color and ball bounce. Har-Tru courts caught on quickly with clubs and homeowners — and a tennis legacy was born.

What is green clay court made of?
A green clay (or Har-Tru) court actually plays more like a hard court than a red clay court.

It’s faster, harder and often far more predictable and lenient with its bounces than red clay.
