Frederick William Wadeley (also spelled Wadely) OBE FRCO (1882 - 1970) was born in Kidderminster in 1882, and was trained at the Royal College of Music and was then at Selwyn College, Cambridge.
He was organ scholar at Selwyn College, Cambridge (1900 – 1903), organist of St. Andrew’s Church, Uxbridge (1903-1904),
organist of Malvern Priory (1904 - 1910) and finally organist of Carlisle Cathedral (1910 - 1960).
"Postlude in D Minor" is the third of the "Three Short and Easy Postludes, Set Two" published by Novello in 1922. It bears the dedication: "To D-A-G" (given in musical notes.

"Postlude in G Minor," the 2nd in the set can be found here:
