After more than 30 years in the business world, Robert Brown retired in 2016 and decided to rent a Delafield office space to spread out his Civil War collection.
Brown, 71, collected maps and books while visiting more than 50 Civil War battlefields around the U.S. over the past 12 years.
"Somebody said that I should really open this up to the public," Brown said. "And I said, 'You know what? I totally should."
Now, he's opening the doors to his museum; he is planning a grand opening for 6:30 to 8 p.m. March 15.
