‘Biological jewels’: the glass models of Herman Oscar Mueller and the role of the specialist museum glassblower (William T. Stearn Student Essay Prize 2022)

Abstract

Bavarian glassblower Herman Oscar Mueller ( fl. 1900s–1960s) was employed for over forty years at the American Museum of Natural History, New York, in his role as a glassblower making intricate glass models of biological subjects. From 1903 to 1945 he produced over one thousand models of invertebrate organisms that combined beauty, morphological accuracy and exceptional glassblowing skill. His talent often surpassed that of the famous Blaschkas of Dresden. Mueller enjoyed worldwide fame in his lifetime, yet his life and models have since fallen into relative obscurity, and few publications record his achievements. In contrast, the Blaschkas are the subject of extensive documentation. To correct this imbalance, Mueller's life and work are here analyzed, drawing on the large collection of primary sources in the Research Library of the American Museum of Natural History, New York, the Library of Congress, Washington DC, and the Rakow Research Library of the Corning Museum of Glass, Corning, New York, amongst others. Mueller's life provides important insights into his highly-specialized role as a museum glassblower, the changing role of natural history collections in the early twentieth century, and the ways in which the lives of important figures can be obscured by a focus on other, better documented individuals.
