André-Marie Ampère (1775-1836) was a French physicist, mathematician, and chemist who founded and named the field of electrodynamics, today known as electromagnetism. His name survives today in the ampere (commonly shortened to amp), the unit of measurement of electrical current. The property was acquired by the city on October 22, 1927 and a playground, originally called the P.S. 64 Playground, opened on the site on June 5, 1958. The name of the park was changed to honor Ampère in 1985.
