The very first swimming pool was built by the Motorenfabrik Oberursel (Motor Pool) in 1927.

The engineer Helmut Stein, who had joined the Motorenfabrik in 1925, initiated the construction of this Werksschwimmbad (factory-run pool for its staff and families). Other facilities, such as sport fields and a shooting range, were added later.
The company supplied the material, and construction was completed by its own workers after working hours.
During the summer months, swimming lessons were given to the young vocational trainees. It soon became a social meeting point for its workers and families.
The city of Oberursel itself had to wait another decade for its own public pool (see postcard). Construction went from 1934 – 1936, and its Grand Opening took place on 7 June 1937.
