President Abraham Lincoln of the United States of America was assassinated by John Wilkes Booth. When he was trying to escape after committing the murder he injured and broke his leg. Dr. Samuel Mudd provided medical help to Booth at that time. He has since been thought of as a co-conspirator in the murder of President Lincoln. He was not convicted because the evidence against him was ambiguous and not concrete. Till date there is a debate amongst the historians if Dr. Mudd was innoncent and the phrase « his name is Mudd » has been coined. This has currently changed to mud instead of Mudd.
