'''Albrecht Preusser ''' (* [[1949]] in [[Beerfelden]]) 
is a [[Germany|German]] [[Engineer]] and [[Geodesist]] known for his numerical algorithms. 

== Life and Work ==
Preusser had a classical education at Ludwig-Georgs-Gymnasium in [[Darmstadt]], from where he graduated in 1967.<ref name="thesis">"Ein dreidimensionales Rechnungsmodell fuer geodaetische Punkt- und Geoidbestimmungen." Dtsch. Geod. Komm. Bayer. Akad. Wiss., Reihe C: Diss., Heft Nr. 238</ref> Among his teachers was [[Otto Buggisch]].<ref>Famous students and teachers at Ludwig-Georgs-Gymnasium[https://de.wikipedia.org/wiki/Ludwig-Georgs-Gymnasium# Bekannte_Sch%C3%BCler_und-Lehrer]</ref> The following years, he studied [[Geodesy]] at the [[Technische Universität Darmstadt]]. From 1972-1977 he served as [[Wissenschaftlicher Assistent|research assistant]] in the Department of Advanced Geodesy and Astronomy at the [[Technische Universität Berlin]].<ref name="webpage">Web-page at Fritz-Haber Institut retrieved 2019-07-08. [https://www.gnz.mpg.de/gnz/pub/preusser.html]</ref>. There, he received his [[Dr.-Ing.|Engineering Doctorate]] in 1977. In his thesis, the suggested interpolation method for [[Geoid]] determination builds on the work of his doctoral supervisor [[Siegfried Heitz]]<ref name="thesis"/>. After a short period as trainee with the office of the Senator for Construction and Housing in Berlin, he worked from 1978-1983 in the Computer Center of the Technical University Berlin. From 1983-1985 he was a member of  "Project Group Parallel Computing", which was merged into the [[Zuse Institute Berlin|Konrad-Zuse-Zentrum]].<ref>. Annual report ZIB 1985[https://opus4.kobv.de/opus4-zib/deliver/index/docid/988/file/JB1985.pdf]</ref> During this time, he developed a number of numerical algorithms for the [[Interpolation]] of [[Isoline|isolines]]. That work was continued in the years 1985-1990 in the Joint Computer Center of the Berlin Max Planck Institutes at the [[Fritz Haber Institute of the Max Planck Society|Fritz Haber Institute]] under the direction of [[Elmar Zeitler]]<ref>Directors at FHI [https://de.wikipedia.org?wiki/Fritz-Haber-Institut_Max-Planck-Gesellschaft#Directoren]</ref><ref>Start of GNZ[http://fhi-berlin.mpg.de/history/h7.epl]</ref>. Preusser’s algorithms are in use worldwide in [[Computer graphics]] software<ref name="webpage"/>.
