I am a HUGE Civil War buff. My guest room is themed and I have been to Gettysburg on multiple occasions. I have a friend who shares this passion as I covered here. I finally found some time to do a new one on the Union side. Joshua Lawrence Chamberlain!
He was an American college professor from the State of Maine, who volunteered during the American Civil War to join the Union Army. He became a highly respected and decorated Union officer, reaching the rank of brigadier general (and brevet major general). He is most well known for his gallantry at the Battle of Gettysburg, which earned him the Medal of Honor.
Jeff Daniels portrayed him in the 1993 movie of Gettysburg and that is the likeness I chose to capture. You can see it available here.
