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

== Life and Work ==
For his schooling, Preusser undertook a traditional classical education at
Ludwig-Georgs-Gymnasium in [[Darmstadt]], from where he graduated in 1967.<ref name="thesis">Ein dreidimensionales Berechnungsmodell für geodätische Punkt- und Geoidbestimmungen. Dtsch. Geod. Komm. Bayer. Akad. Wiss., Reihe C: Diss., Heft Nr. 238, p. 102</ref> Amongst 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> In 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]]. There, he received his [[Dr.-Ing.|Engineering Doctorate]] in 1977. 
His doctoral thesis proposed a new mathematical interpolation method for [[Geoid]] determination which builds on the work of his doctoral supervisor [[Siegfried Heitz]]. It was accepted for publication by the “Deutsche Geodätische Kommission bei der Bayerischen Akademie der Wissenschaften“, an independent and reliable publisher for important geodetic research results in Germany.

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 name="IMSL">Biography "IMSL Directions" Vol. 2 1985, No. 3, p. 2</ref> <ref>Annual report ZIB 1985[https://opus4.kobv.de/opus4-zib/frontdoor/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 name="IMSL"/><ref>Directors at FHI [https://de.wikipedia.org/wiki/Fritz-Haber-Institut_der_Max-Planck-Gesellschaft#Direktoren]</ref><ref>Start of GNZ[http://www.fhi-berlin.mpg.de/history/h7.epl]</ref>

Preusser’s algorithms and ideas are in use worldwide in [[Computer graphics]] software, for instance commercial  products like  [[Rogue Wave Software]]<ref name="Rogue">Rogue Wave Software Contour2 [https://docs.roguewave.com/en/pv-wave/current/PVWAVE_Online_Help/pvwave.html#page/Foundation%2Fcontour2.html]</ref>, and public domain graphic packages like GraceGTK derived from [[Grace (plotting tool)|Grace]] <ref>GraceGTK contours [https://sourceforge.net/p/gracegtk/code/ci/master/tree/contours/toms626_modified.f]</ref>. Many research projects like "Analytically defined Surfaces to analyzed molecular interaction Properties" from the European Molecular Biology Laboratory, Heidelberg, used his software "xfarbe" for the visualization of surfaces.<ref name="Wade">Usage at European Molecular Biology Laboratory [https://projects.hits.org/dbase/molsurfer/ads/mgms/mgms_o.html]</ref>

Three Algorithms with accompanying papers were accepted for publication by  [[Association for Computing Machinery|ACM]] during 1984-1990, the world’s largest scientific and educational computing society, and widely accepted as authority in the field. These contributions to the international community are of enduring value and continue to remain popular, as the number of recorded downloads show. The first ''Algorithm 626: TRICP: A contour plot program for triangular meshes'' from 1984 has been downloaded more than 1000 times since 2004.<ref name="ACM">Downloads of ACM Alg. 626 [https://dl.acm.org/citation.cfm?id=2772]</ref>. It allows for contour plotting of scattered data in the plane without first interpolating a regular grid. This approach yields more accurate contour lines and is very useful in the visualization of results from the [[Finite element method]].
