notes: label: Description
content: As a student of Alexander Brill in Munich, Georg H. L. Sievert designed this plaster model of a surface of revolution. Sievert would spend much of his career teaching mathematics in Nuremberg and Bayreuth. The model would be published by Ludwig Brill of Darmstadt in 1885 as the last of the models in his Series 10, 30 (lettered 30a through 30m and given Brill numbers 113 to 124). This is letter “30m” in that series. When Martin Schilling took over Brill’s business, he changed the numbers to Series 10 # 10a through Series 10 #10m (196 through 207). This would be “10m” in that scheme, with model number 207.
