- de.wikipedia.org, "Ernst Gehrcke" (API fetch) [web]: Gehrcke (d. 1960) worked at the Physikalisch-Technische Reichsanstalt 1901-1946 and "zählte neben Paul Weyland, Philipp Lenard und Johannes Stark zu den bekanntesten Antirelativisten"; collected newspaper clippings on Einstein, basis of his "Massensuggestion der Relativitätstheorie"; wrote Kritik der Relativitätstheorie. His NDB entry is by Ernst Lau, his co-author. (The deutsche-biographie.de URL guessed by script returned a different person; not retried.)
