Bernard D. (Bernard Dell) Bolas

Bernard D. Bolas, also listed as Bernard Dell Bolas, is known for A Handbook of Laboratory Glass-Blowing, a work published in the early 1920s and now available through public-domain collections. The book focuses on the craft of making and shaping laboratory glassware, suggesting an author with strong practical knowledge of scientific technique.

Library and archival records also connect the name Bernard D. Bolas with Glass-blowing, Applied to Laboratory Work, and the Wellcome Collection lists him as an author connected with medical and scientific materials. A surviving First World War record also appears under the name Bernard Dell Bolas, though biographical details beyond that are limited in the sources I could confirm.

Because so little dependable personal information is readily available, Bolas is best introduced through his work: clear, useful writing aimed at helping readers master a demanding technical skill. For listeners interested in the history of science, laboratory practice, or old-school craftsmanship, his books offer a direct window into how practical knowledge was taught a century ago.
