Sir Ifor Williams (16 April 1881 - 4 November 1965) was a Welsh scholar who laid the foundations for the academic study of Old Welsh, particularly early Welsh poetry.

Ifor Williams was born at Pendinas, Tregarth near Bangor, Wales the son of John Williams, a quarryman, and his wife Jane. His maternal grandfather, Hugh Derfel Hughes, was a noted local historian who wrote a well-regarded book on the history of the area. He went to Friars School, Bangor, in 1894 but had only been there for just over a year when he suffered a serious accident. This left him with back injuries that made him bedridden for several years.

Having recovered, he attended Clynnog School in 1901 and in 1902 won a scholarship to the Bangor University. In 1905 he graduated with honours in Greek, then in 1906 in Welsh. He spent the 1906-07 academic year at the Department of Welsh working for his M.A. degree and assisting Sir John Morris-Jones, the Professor of Welsh, before being appointed an assistant lecturer. In 1920 a Chair of Welsh Literature was specially created for him, which he held until Sir John Morris-Jones died in 1929, when he became Professor of Welsh Language and Literature.

Professor Ifor James (August 30, 1931 – December 23, 2004) was a horn player and teacher, numbering among his pupils many future Principal Horns and horn professors at British music schools.

James was born in Carlisle, England; his father was a noted cornet player and his mother a famous soprano. He began playing cornet in a brass band at age four and by seven he was playing paying gigs as a trumpeter. He also played the organ and was assistant organist in Carlisle Cathedral. Taking up the horn in 1951, he studied first privately and then under Aubrey Brain at the Royal Academy of Music. His professional horn playing career began with the Halle Orchestra then the Royal Liverpool Philharmonic Orchestra, and was much in demand for chamber recitals and solo work.

Moving to London, he played as principal horn with many orchestras and chamber groups. He was appointed professor of horn at the Royal Academy of Music, principal horn of the English Chamber Orchestra, and horn player in the Philip Jones Brass Ensemble, with whom he toured the world and made over 30 recordings. He was also appointed professor for horn at the Royal Northern College of Music (Manchester). His final teaching appointment was as professor for horn at the Staatliche Hochschule für Musik, Freiburg, Germany.
