He was the inventor of the relascope, a method for efficient forest inventory.<ref>Burkhart, H.E., 2008. Remembering Walter Bitterlich ''Journal of Forestry'', Vol. 106, No. 2., p. 61. http://saf.publisher.ingentaconnect.com/content/saf/jof/2008/00000106/00000002/art00001</ref>

== Early career == Bitterlich descended from several generations of foresters and did much of his early work in the Tyrolean Alps of Austria.

Walter Bitterlich was the son of the forester Ernst Bitterlich and his wife Maria née Wachtel. Despite his upbringing in relative poverty, he successfully completed a forestry degree at Vienna's University of Natural Resources and Life Sciences in 1930 and the state exam for Higher Forest Service in 1933. Failing to find regular employment, he started volunteering with the Austrian State Forestry Commission.

==National Socialism== Bitterlich was an early member of the National Socialist German Workers' Party, joining in 1933 when it was illegal to do so in Austria. After the Anschluss of Austria in 1939 he became party member no. 511,075 (later changed to 1,618,531).<ref name="Maria">{{Cite book|last1=Rathkolb|first1=Oliver|url=https://www.vr-elibrary.de/doi/book/10.7767/boehlau.9783205790419|title=Die "Reichsforste" in Österreich 1938-1945: Arisierung, Restitution, Zwangsarbeit und Entnazifizierung .

This was essential for gaining employment with the national forest service, where, in 1937, three of every four employees held that distinction.<ref>{{Cite book|url=https://books.google.com/books?id=njZOAQAAIAAJ&q=Walter+bitterlich+nsdap|title=Profil|date=2010-03-05|publisher=Verlagsgruppe News|location=Vienna|pages=40|language=de}}</ref> Thus qualified, he was made forest inspector of his native district of Reutte in 1938, 30 years after his father held the same position. In 1942 he was drafted into military service, first at the Eastern Front and, starting in 1943, Normandy. His war memoirs, published in 2003, describe the sense of adventure and camaraderie he found during this time and his insights into the application of military thinking to forest trees.<ref>[https://web.archive.org/web/20110726132840/http://www.growthmodel.org/wmens/m2009/iles.ppt Growth Model] </ref> They do not mention the party he eagerly joined a decade before.<ref>{{Cite book|last=Bitterlich|first=Walter|url=https://books.google.com/books?id=WxRnAAAAMAAJ&q=nsdap|title=Kriegserinnerungen: persönliche Aufzeichnungen von 1942 bis 1945|date=2003|publisher=Ehrenberg-Verlag|isbn=978-3-901821-03-5|language=de}}</ref>

After the war, the Nationalsozialistengesetz required his dismissal from public service. Unemployed and short on cash, he brought his young family to Salzburg, where they moved in with his parents. His fate soon turned, however, as Austria started to redefine its role as a victim, not perpetrator, of Nazi aggression. The 1947 changes to the law removed early party membership as a decisive factor in denazification and created a category of "minor offenders" that allowed many party members to resume their careers with little resistance.<ref>{{cite book | author = Brigitte Bailer-Galanda | author-link = Brigitte Bailer-Galanda | chapter = 'Revisionism' in Germany and Austria: The Evolution of a Doctrine | title = Antisemitism and Xenophobia in Germany After Unification | url = https://archive.org/details/antisemitismxeno00kurt | url-access = limited |editor1=Hermann Kurthen |editor2=Werner Bergmann |editor3=Rainer Erb | publisher = Oxford University Press | year = 1997 | isbn = 0-19-510485-4 | page = [https://archive.org/details/antisemitismxeno00kurt/page/n204 188]}}</ref> Thus, Bitterlich was reinstated in 1948, serving in Zell am See, and, from 1953 to 1967, Hallein.<ref name="Maria" />

==Scientific Career== Beginning in 1948, Bitterlich developed a method of plotless sampling for forest inventory. His process was first published in 1948 and presented at the World Forestry Congress in Helsinki the following year. Also in 1949, he was awarded a doctoral degree by the University of Natural Resources. In 1967, he returned to his ''alma mater'' as full professor.

From 1949, he worked on commercialising his method with industry partners. From 1962, his company ''Feinmechanische Optische Gesellschaft'' developed and sold the relascope and other optical instruments with applications in forestry and the military.

With his wife Ilse, Bitterlich had four children. He died in his native Reutte on February 9, 2008, 10 days short of his centennial.

==Honours and awards== * Honorary citizen of Nashville, Tennessee * Corresponding member of the Finnish Forest Research Institute * Honorary Member of the Society of American Foresters (1971) * Golden insignia of the Land of Salzburg * Cross of Honour for Science and Art, 1st class (1983)<ref>{{cite web | url = http://www.parlament.gv.at/PAKT/VHG/XXIV/AB/AB_10542/imfname_251156.pdf | title = Reply to a parliamentary question | language = German | page=664 |trans-title=| accessdate = 22 October 2012 }}</ref> * Golden Medal of Reutte
