Mathematics illuminates the patterns that abound in our world.  The National Museum of Mathematics strives to enhance public understanding and perception of mathematics. Its dynamic exhibits and programs stimulate inquiry, spark curiosity, and reveal the wonders of mathematics.  The Museum’s activities lead a broad and diverse audience to understand the evolving, creative, human, and aesthetic nature of mathematics.

Brief history

The National Museum of Mathematics began in response to the closing of a small museum of mathematics on Long Island, the Goudreau Museum.  A group of interested parties (the “working group”) met in August 2008 to explore the creation of a new museum of mathematics — one that would go well beyond the Goudreau in both its scope and methodology.  The group quickly discovered that there was no museum of mathematics in the United States, and yet there was incredible demand for hands-on math programming.

Accomplishments to date include: opening Manhattan’s only hands-on science center, welcoming more than one million visitors; creating the popular Math Midway exhibition, which has delighted millions of visitors at museums throughout the United States and internationally; leading math tours in various U.S. cities; running dozens of Math Encounters and Family Fridays events; delivering a broad array of diverse and engaging programs for students, teachers, and the public to increase appreciation of mathematics; and creating the largest public outdoor demonstration of the Pythagorean Theorem ever.


The Museum is governed by a Board of Trustees, receives intellectual guidance from an Advisory Council, and operates with the assistance of the working group and other volunteers.  John Overdeck serves as Chair of the Board of Trustees of the Museum, and Cindy Lawrence as the Museum’s Executive Director and CEO.


The Museum received its provisional charter from the New York State Department of Education on November 17, 2009 and its absolute charter on September 15, 2015.

Diversity, Equity, and Inclusion

The National Museum of Mathematics respects, values, and celebrates an equitable, diverse, and inclusive world.  MoMath strives to be an anchor in the mathematics community that helps to build awareness and understanding among diverse people, and the Museum is committed to creating an inclusive and welcoming environment for all.

Black Lives Matter

The National Museum of Mathematics stands in solidarity with the Black community and opposes all forms of racism, violence, and discrimination.  Through its work, the Museum strives to create a more just, tolerant, and enlightened society.

The National Museum of Mathematics is the owner of U.S. Patent Nos. 8,602,790; 9,165,479; and 9,472,120 covering one or more exhibits in the Museum.
