Darwin Day Program and Darwin Day Celebration

In the late 1990s, two Darwin enthusiasts, Amanda Chesworth and Robert Stephens, co-founded an unofficial effort to promote Darwin Day. In 2001, Chesworth moved to New Mexico and incorporated the "Darwin Day Program". Stephens became Chairman of the Board and President of this nonprofit corporation with Massimo Pigliucci

 as Vice-President and Amanda Chesworth as member of the Board, Secretary, and Executive Director.
Stephens presented the objectives of the organization in an article titled "Darwin Day An International Celebration."

In 2002, Chesworth compiled and edited a substantial book entitled Darwin Day Collection One: the Single Best Idea, Ever. The objectives of the book were to show the multidisciplinary reach of Charles Darwin and to meld academic work with popular culture.

In 2004, the New Mexico corporation was dissolved and all its assets assigned to the "Darwin Day Celebration", a non-profit organization incorporated in California in 2004 by Dr. Robert Stephens and others
and the Mission Statement was expanded.

Darwin Day Celebration redesigned the Web site, DarwinDay.org, from a static presentation of information about the Darwin Day Program to a combination of education about Darwin and the Darwin Day Celebration organization, including automated registration and publication of planned and past celebratory Events and the automated registration of people who want to receive emailings or make public declaration of support for Darwin Day. The website is now operated by the International Darwin Day Foundation, an autonomous program of the American Humanist Association

The resolution states, “Charles Darwin is a worthy symbol of scientific advancement… and around which to build a global celebration of science and humanity.” The resolution was a culmination of collaboration between Rep. Stark and the American Humanist Association, which honored Stark with the Humanist of the Year award in 2008. In a statement on the House floor, Rep. Stark said, "Darwin's birthday is a good time for us to reflect on the important role of science in our society." In a press release from the American Humanist Association, executive director Roy Speckhardt said, "Stark's Darwin Day resolution is a thrilling step forward for the secular movement. Not only is this an opportunity to bring the scientific impact of Charles Darwin to the forefront, but this also signifies the potential for greater respect for scientific reasoning on Capitol Hill."
