Johan Keller

Johan Christopher Henrik Rummelhoff Keller (7 June 1830 – 20 May 1884) was a Danish educator, theologian and professor and the founder of the Keller Institution in 1867.

Early Life, family and education

Keller was the son of Christian Nicolai Keller (29 September 1802 – 10 September 1884) an inspector of a reformatory in Copenhagen and Sophie Henriette Magdalene Pers (16 October 1798 – 15 September 1859). Keller completed secondary school in 1849 and then began studying theology at the University if Copenhagen, which he completed in 1855.

Career

In 1856 Keller became the head of school for the deaf-mute, however as this was a small school of only seven pupils, Keller had to find additional employment as a municipal schoolteacher. Keller started his own institution for mentally deficient people in 1856 and over the next twenty-eight years established five different institutions for; deaf and dumb children; feeble-minded deaf mutes; deaf-dumb women; feeble-minded children; and an asylum for idiots.

By 1865 Keller was teaching children who were stammering or lisping at his school at 59 St. Kongensgade, however this building became too small as the number of pupils rose up to 70 students. In 1869 the school moved first to Baggesensgade and then it moved to Karens Minde in 1880, which is now a public library and cultural building. Alongside Rasmus Malling-Hansen, Keller helped found the 'Association of Friends of the Abnormal School' on 2 December 1876, which was established to support and promote the welfare of the blind, deaf-mute and mentally disabled. The first General Assembly was held on the 29 January 1877, where the association was formally constituted. Despite public disagreements in 1883 between Keller (De Kellerske Anstalter), Malling-Hansen (Royal Deaf-Mute Institution in Copenhagen) and Jørgensen (Royal Deaf-Mute Institute in Fredericia) that revolved around pedagogy, administrative authority and Keller's state-supported institutes, the association was still active in 1903.

By 1884, the now established Kellerske Institutions was looking after 600 people across seven different locations. Keller died suddenly in 1884 and his work was continued by his brother Emil and his son, Christian, took over as director of the Kellerske Institutions.
