What is an alternate name for a universal joint that is also the last name of an English natural philosopher, architect and polymath?
Universal joint A universal joint (universal coupling, U-joint, Cardan joint, Spicer or Hardy Spicer joint, or Hooke's joint) is a joint or coupling connecting rigid rods whose axes are inclined to each other, and is commonly used in shafts that transmit rotary motion. It consists of a pair of hinges located close together, oriented at 90° to each other, connected by a cross shaft. The universal joint is not a constant-velocity joint.
Harold Arthur Prichard Harold Arthur Prichard (1871–1947), usually cited as H. A. Pritchard, was an English philosopher. He was born in London in 1871, the eldest child of Walter Stennett Prichard (a solicitor) and his wife Lucy. Harold Prichard was a scholar of Clifton College from where he won a scholarship to New College, Oxford, to study mathematics. But after taking First Class honours in mathematical moderations (preliminary examinations) in 1891, he studied Greats (ancient history and philosophy) taking First Class Honours in 1894. He also played tennis for Oxford against Cambridge. On leaving Oxford he spent a brief period working for a firm of solicitors in London, before returning to Oxford where he spent the rest of his life, first as Fellow of Hertford College (1895–98) and then of Trinity College (1898–1924). He took early retirement from Trinity in 1924 on grounds of ill health, but recovered and was elected White's Professor of Moral Philosophy in 1928 and became a fellow of Corpus Christi College. He retired in 1937.
