Junior high school mathematics teacher and veteran Michael Landsberry sacrificed his life to save as many as 30 students from a teen gunman.

Sometimes it is sobering to remember what a heavy responsibility we teachers have when it comes to protecting our students from harm. And there are many examples of heroic educators who have paid the ultimate price to protect their kids. One such hero is Michael Landsberry, a junior high school math teacher from Reno, Nevada.

Following his graduation from high school in 1986, Michael served in the United States Marine Corps where he had risen to the rank of corporal. He served two tours of duty in Afghanistan, and later became a member of the Nevada Air National Guard.

After his discharge, Michael attended college at Nevada State University, Reno, on the GI Bill. There he earned his Bachelor’s degree in Mathematics in 2001. Following his college graduation, Michael accepted a teaching position at Sparks Middle School in Sparks, a suburb of Reno, Nevada. In addition to being a math teacher, he also coached basketball, cross country, track, and volleyball, and he served as the girls soccer coach at Sparks High School. Michael quickly became a beloved teacher known for pushing his students, but doing it with love and compassion.

On October 22, 2013, Michael was getting ready for the morning bell, when a 12-year-old student suddenly opened fire on his classmates. After the first student was shot, the chalkboard champion’s military training in kicked in. He calmly walked toward the shooter, putting his hands up in a motion to try to talk the youngster into giving up his gun. The student shot him in the chest at point blank range. Michael later succumbed to his injuries, but his heroic actions gave the other students on the playground time to run to safety. He is credited with saving as many as 30 lives that day.

For his heroism, Michael’s name has been inscribed on the Memorial to Fallen Educators at the National Teachers Hall of Fame in Emporia, Kansas.
