In 2006 the Goudreau Museum on Long Island, at the time the only museum in the United States dedicated to mathematics, closed its doors. In response, a group led by founder and former CEO Glen Whitney met to explore the opening of a new museum. They received a charter from the New York State Department of Education in 2009, and raised over 22 million dollars in under four years.

With this funding, a 19,000 square feet (1,800 m2) space was leased in the Goddard Building at 11-13 East 26th Street, located in the Madison Square North Historic District. Despite some opposition to the architectural plans within the local community, permission for construction was granted by the New York City Landmarks Preservation Commission and the Department of Buildings.

On August 2, 2018 MoMath announced the creation of a Distinguished Chair for the Public Dissemination of Mathematics. Princeton professor and Fields Medal winner Manjul Bhargava was named as the first recipient of this position.
