The city opened the egg-shaped Moores Park Pool in 1923, making it one of the oldest public pools still in operation in the country.

When it opened, city officials dedicated the public space as the "J.H. Moores Memorial Natatorium" after the Lansing real estate and lumber baron whose donations of land started Lansing's park system.

Wesley Bintz, a former city engineer, designed the pool.  After 1923, he decided to design pools full time and began the Bintz Pool Company.  He brought his design to more than 100 cities across the U.S.

The Lansing design itself is a little different than other pools, you can tell that he really was still playing around with aesthetics.  Here's more from the Lansing State Journal.
