History of the Mastodon Fair

Dorothy Boyer Heinze founded the Mastodon Art/Science Connection Fair in 1979 in conjunction with early fundraising events for the Mastodon Park, now called the Historic Site. The Mastodon Park Committee held the Fair from 1979-1993 at the Historic Site which was adequate for the 15-165 students that participated. In 1991, Eva Kirkpatrick became director of the Fair and due to the growth in participants, the Fair was moved to Jefferson College in Hillsboro. The Mastodon State Historic Site now displays winning projects for public viewing at the museum each year.

In 1992, the Fair became a 501(c)3 organization separate from the Mastodon Historic Site. We receive no state or federal funding, and all of the operating and award expenses must be raised each year. The Mastodon Park Committee continues to be a sponsor of the Fair.

After negotiations with the Greater St. Louis Fair, the Mastodon Fair received their Regional Charter on August 7, 1997. The affiliation with the Science Service in Washington, D.C. followed in September, 1997. Vera McCullough, Eva Kirkpatrick’s daughter, became director of the Fair in Spring 2000. During her directorship, the Fair integrated technology solutions enabling the processing of each of the 2000+ students in one day as well as sending the first ever observers to the International Fair. In Spring 2002, there were a total of 2500 entries with 1700 Art projects and 800 Science projects entered into the Fair.

The transfer of the director position to Jill (Thomas) Malcom, an original participant in the Fair in 1979, occurred in the Spring of 2002. By 2005, the Fair held the status of being the largest combined Art and Science Fair in the United States and started using an invented online registration system to automate the entry process. In order to sustain the growth, full-time leadership was needed, and on July 1, 2006 the Fair hired Jill Malcom as the first full-time paid Executive Director position. Previously, from 1979 to 2006, the Fair had been completely run by volunteers.
