Thomas Edmondson (30 June 1792 in Lancaster, England – 22 June 1851 in Manchester, England) was the inventor of the Edmondson railway ticket. He was a member of the Religious Society of Friends and originally worked in the Lancaster cabinet making business of Gillow. When the Manchester and Leeds Railway opened in 1839 Edmondson became the company's chief booking clerk at Manchester. His machines and their improved successors quickly became the standard for British and other railways. He died a wealthy man; members of his family carried on the business for many years afterwards.
