Arthur Herman Gilkes MA, (1849 – 13 September 1922) was a noted educationalist, author, and clergyman, and was Master of Dulwich College from 1885 to 1914.
He was born in Leominster, the son of William Gilkes a chemist. He was educated at Shrewsbury School and went on to Christ Church, Oxford from where he received a First Class Honours degree in Literae Humaniores in 1872 having achieved a first class in Mods in 1870. He received his MA in 1885. On 19 May 1892 he married Millicent Mary Clarke, the daughter of Bennett Michell Clarke, and sister of three brothers who attended Dulwich College. He had four sons (all of whom went to Dulwich College) and one daughter, one of whom, Christopher would later also become the Master of Dulwich College. Another son Humphrey became a doctor, and was one of four soldiers to be awarded the Military Cross on four occasions in the First World War.
Having completed his education he went on to become Assistant Master from 1873 to 1885 at Shrewsbury School. From Shrewsbury he left for London to become the Master of Dulwich College from 1885 to 1914. The work he did at Dulwich College raised its reputation considerably, and he did this with only modest financial resources. During his tenure Dulwich became renowned for a number of areas notably including engineering and science. It was also A H Gilkes who first accepted London County Council scholars from elementary schools.
His connections to Dulwich went beyond those of an administrator and a teacher, for he also had extensive family ties with the school. All four of his sons attended, as did his three brothers-in-law, three nephews and his first cousin.
