A friend of the family, Rev. Nathaniel Boyse, arranged to have Curran educated at Midleton College, County Cork. He studied law at Trinity College, Dublin (he was described as "the wildest, wittiest, dreamiest student") and continued his legal studies at King's Inns and the Middle Temple. He was called to the Irish Bar in 1775. Upon his first trial, his nerves got the better of him and he couldn't proceed. His short stature, boyish features, shrill voice and a stutter were said to have impacted his career, and earned him the nickname "Stuttering Jack Curran".
