Gustav Woldemar Freiherr von Biedermann (5 March 1817, Marienberg – 6 February 1903, Dresden) was a jurist, literary historian, and Goethe researcher.
The son of the jurist and politician Gustav Heinrich Freiherr von Biederman, Woldemar von Biedermann studied legal science in Leipzig and Heidelberg from 1836 to 1839.
In 1849 he found employment in the railway industry first as the government commissioner to the Executive board of the Chemnitz-Riesa railway company (German: Chemnitz-Riseaer Eisenbahngesellschaft), as railway director in Chemnitz in 1851, in Leipzig in 1858, and in 1869 as Finance and Deputy Director-General of the Royal Saxon State Railways–a cabinet post.
His son, Flodoard von Biedermann, urged him to publish his assemblage of recorded conversations of Goethe.
Other published writings include more than 180 critical and technical contributions to the Goethe literature.
