In 2017, Mr. Stemm was honoured with the Freedom of the City of London Award, one of the oldest surviving ceremonies in existence. The prestigious award is believed to have been first presented in 1237 and has included such notable figures as Sir Winston Churchill, Florence Nightingale, Bill Gates and Charles Lindbergh. Mr. Stemm received his illuminated Freedom scroll at a ceremony presided over by the Mayor of the City of London, followed by a banquet at Guildhall on September 3, 2017. The honour historically provided special trading rights and privileges (including the right to go about the City with a drawn sword and take their livestock tax free over the London Bridge) to individuals who have provided exemplary service to the UK and the City of London and have shown success and recognition in their chosen field.
