Dr. Martin Horejsi is a Professor of Instructional Technology and Science Education at The University of Montana, Missoula. A long-time meteorite collector and writer, before publishing his column "The Accretion Desk" in The Meteorite Times, he contributed often and wrote the column "From The Strewnfields" in Meteorite Magazine. Horejsi is also the Lead Technology Reviewer for The National Science Teaching Association, and just celebrated his 22th year working with NASA and the JPL in education and public outreach (EPO), and is a NASA Solar System Ambassador. Horejsi specializes in the collection and study of historic witnessed fall meteorites with the older, smaller, and rarer the better. Although his meteorite collection once numbered over a thousand pieces with near that many different locations, several large trades and sales and trades have streamlined the collection to about 250 important locations with all but 10 being witnessed falls. Many of the significant specimens in Horejsi's collection are historic witnessed falls that once occupied prominence in the meteorite collections of Robert A. Haag, James Schwade, and Michael Farmer. Other important specimens were acquired through institutional trades including those from The Smithsonian Institution, Arizona State University, and other universities. Horejsi was awarded the Harvey (Nininger) Award in Tucson in 2006, The Brotherhood of Guardians of the Ensisheim Meteorite in 2011, a JPL Inspiration Person, on the JPL STARDUST Team that was awarded the Smithsonian Air and Space Museum Annual Trophy in 2008, and former board member of the International Meteorite Collectors Association, and the Northwest Council for Computers in Education.
