Harry had always been a sort of patriot,so when WWI broke out it was no surprise that the legendary escape artist would immediately hit the streets just like everyone else was doing in an attempt to assist the soldiers of America and contribute towards to war effort. He began to sell war bonds as often as he could, wherever he was, and even taught soldiers the art of escaping from German handcuffs. He also performed plenty of unofficial shows for the soldiers going to and coming from the battlefields. Surely there were some very grateful soldiers later on.
Of course, the war didn't stop the young magician from studying his magic. All the while he continued to practice and learn new magic tricks. At one point he even performed for President Theodore Roosevelt. Those years, from 1914 to around 1916 were some of the busiest for Houdini. Not only was the escape artist involved in an affair, but he also had a near death experience during a buried alive skit.
