It takes a certain person to rise to the rank of commander in chief; but even they have a few things to learn.
Every president needs to pick up a few tricks of the trade while in oval office; and for some of them that includes the biggest inventions of our time. For example William Henry Harrison, the 9th president of the United States was the first sitting president to be photographed. But the photo from that day has been lost. So a photo of John Quincy Adams taken long after his time in office was over is considered the first photograph of a president.
A few years later Abraham Lincoln earned his spot on the list of presidential tech firsts by being the first to send a telegram. He pioneered the use of the communication device during the Civil War. His successor Andrew Johnson then had the first telegraph room built in the White House.
To see which presidents are credited for some other firsts including electricity, phones and television use the link below. Everyone loves the next big thing.
