The American Museum of Natural History will celebrate 105-year-old philanthropist Kathryn W. Davis at a special ceremony and luncheon today to celebrate her generous support of the Museum’s new Master of Arts in Teaching (MAT) Program, the first freestanding master’s degree program offered by a museum to prepare science teachers. The ceremony will also include the official dedication of the new Kathryn W. Davis Science Teaching Classroom, which will be the main educational center for candidates in the MAT program.
