Frederick Ouseley
Sir Frederick Arthur Gore Ouseley, 2nd Baronet was an English composer, organist, musicologist and priest.
He was born in London, the son of Sir Gore Ouseley, and manifested an extraordinary precocity in music, composing an opera at the age of eight years. In 1844, having succeeded to the baronetcy, he entered at Christ Church, and graduated BA in 1846 and MA in 1849. He was ordained in the latter year, and, as curate of St. Pauls Church, Knightsbridge, served the parish of St. Barnabas, Pimlico, until 1851.
