Francis Rynd

Francis Rynd was an Irish medical doctor known for inventing the hypodermic needle used in syringes in 1844, which also led to the first recorded injection. Born in Dublin in 1801, he attended medical school at Trinity College Dublin, became a member of the Royal College of Surgeons in Ireland in 1830, and worked at the Meath Hospital in Dublin, where he trained under Sir Philip Crampton. He also served as medical superintendent of Mountjoy Prison. In a 1845 article in the Dublin Medical Press he described injecting morphia solution near the nerves of a patient on 3 June 1844 with an instrument made for the purpose. He died in 1861.
