Henry Miller Shreve (1785-1851) wasn't just the subject of the first-ever Hallmark Hall of Fame episode; he was a significant figure in American history, particularly in the realm of river navigation. He played a crucial role in developing and navigating steamboats during the early 19th century. Notably, he captained the Enterprise, the second steamboat on the Mississippi River, and even participated in the Battle of New Orleans during the War of 1812.
