Draft:Corn. Alb. Kloekhof M. D.

Cornelius Albertus Kloekhof (also: Kloekhoff, Cloeckhof, Klockhof, Klockof, Klökhof, Kloeckhof or Kloeckhoff; his first name can be found as Cornelius, Cornelis of Kornelis) (Culemborg, baptized on the 29th of September 1715 - Culemborg, 25th of February 1788 ), was a Dutch physician and politician, and a foundational figure in the history of psychiatry, especially ADHD.

Biography
He was the son of of Balthasar Kloeckhoff (1680-1764) and Maria de Lange (1680-1756).

He studied Medicine in Leiden with Hermannus Oosterdijk Schacht and Hieronymus David Gaubius from the 10th of December 1732 until the 24th of July 1736, when he defended his thesis.

In 1737 he became the city doctor at Culemborg. There, he also becomes schepen on the 1st of May 1747 and finally, like his father and many others from his family, he becomes Mayor on the 2nd of July 1758 until at least 1773, but no later than 1780. In his home town, he befriended the politician and lawyer Abraham Perrenot.

In 1755 he was nominated for the Chair of Medicine at the University of Harderwijk to succeed David de Gorter, but in the end, he was not chosen for this position. From the 21st of May 1760, he was a member of the Hollandsche maatschappye der weetenschappen (the Scientific Society of Holland, currently named the Koninklijke Hollandsche Maatschappij der Wetenschappen), for which he wrote several articles. He also was a member of the Natuur- en Geneeskundige Correspondentie-Sociëteit (the Correspondance Society for Natural and Medicinal Science) from 1780.

His works are plentifully cited in the Netherlands and in international literature. Some of his works have been translated into German.

Two of his works recieved special attention:

His discription of an epidemic in Culemborg in the year 1741 (in his Opuscula Medica), which is cited in many works on infection troughout the eighteenth and nineteenth century.

The second work that was quite inluential was het work on mental illnesses: "De morbis animi", in which he put forth a vision that was very much ahead of his time. Many physicians that laid the foundation of psychiatry cite Kloekhof as inspiration and an important predecessor (e.g. Weikard, Tissot and Reil ). Through this work, Kloekhof probably started the long research on ADHD.

He died in Culemborg on the 25th of February 1788 and was buried in the St. Barbara Church on the 28th of February 1788.
