John Julian (27 January 1839 – 23 January 1913)[1] (no middle name on birth certificate) was a Church of England clergyman, known as the editor of A Dictionary of Hymnology.[2] Throughout the twentieth century and into the twenty-first this was the common reference for those studying hymnody and hymnology. His own estimate was that there were 400,000 hymns in the scope of his chosen field; his correspondents for research numbered over 1000.[3] It was only superseded over a century later by the online Canterbury Dictionary of Hymnology.[4]
