Ábrahám Géza Pattantyús was the educator of a generation of engineers, and founder of the "Pattantyús school". He wrote several textbooks, the most important being the "Gépek üzemtana" (Machine Manage-ment), which underwent 14 printings.

His work was characterized by a close coordination of scientific theory with actual practice. The process by which the correct size of the pressure tank of displacement pumps is determined is known around the world as the Pattantyús method.
