During this weekend’s Memorial Day observances, I am reminded that many our our nation’s educators are also veterans. One of my favorite Chalkboard Heroes is Henry Alvin Cameron, a high school science teacher from Nashville, Tennessee. He was not only a leader in the African American community in the early days of the 20th century, but he was also a veteran of World War I. Below is a digital story I created to tell you more about this heroic historical figure.
