Pinches was originally employed in father's business as a die-sinker, but, following an amateur interest in cuneiform inscriptions, joined the staff of the British Museum in 1878, working there as assistant then curator till retirement in 1900.
[1] During his tenure at the Egyptian and Assyrian Department, British Museum, he gave assistance to scholars including Abraham Sachs and taught at London University.
[3] In 1890, Pinches discovered and published the correct reading of the name of Gilgamesh, instead of Izdubar.
[4] The document known as Chronicle P - providing important historical information despite its bad condition - is named for Pinches, who was its first editor.
Pinches died in 1934 and "bequeathed much of his large personal collection of cuneiform tablets" to a favorite student, Archibald Cecil Chappelow.
