Friedrich Fischer Wikipedia

Fischer designed the ball grinding mill, a machine that allows steel balls to be ground to an absolutely round state in large volumes for the first time. Thanks to this innovation, he laid the foundation for the entire rolling bearing industry. Thus, the worldwide success story of the ball bearing begins in Schweinfurt. Later, 1883 is officially declared the year in which the company was founded.
