Biography
Edward Ball Knobel, born in London on October 21, 1841, lived until July 25, 1930, reaching the age of 88. Throughout his life, he ventured into various careers, including law, chemistry, industrial management, and amateur astronomy, dedicating himself seriously to each. Although he never held an academic post in astronomy, his work earned him recognition among prominent scientific societies of his time.
Knobel started with law but soon shifted to geology at the Government School of Mines (now part of Imperial College London) in 1861. However, by the next year, he left geology to join Bass and Company in Burton upon Trent as an analytical chemist in the brewery department. He excelled in this field, moving up to roles such as manager and Head Brewer. In 1875, he took a managerial job at a Courtauld's silk factory in Bocking, Essex, and eventually worked at the Ilford Photographic Company, which was pioneering new developments in photography.
In 1872, Knobel bought an 8.5-inch reflecting telescope, marking the start of his deep dive into astronomy. His 1875 project on star catalogues led him to study early Arab astronomy, prompting him to learn Arabic and Persian to access original texts. This effort allowed him to study medieval astronomical manuscripts directly.
Knobel collaborated extensively with C. H. F. Peters on a new edition of the star catalogue in Ptolemy's Almagest, drawing from sources in Greek, Arabic, and Latin. This exhaustive study culminated in a publication in 1915 after decades of work. In 1917, he also released an English translation of Ulugh Beg's star catalogue, strengthening his reputation as an expert in historical astronomy.
Knobel was President of the British Astronomical Association and twice led the Royal Astronomical Society from 1892 to 1893 and from 1900 to 1901, underscoring the esteem in which his peers held him. His career shows how dedicated self-study, combined with language skills and perseverance, can yield significant scientific achievements outside traditional academic settings.
Before Fame
Edward Ball Knobel grew up in Victorian London, a time when focusing on self-improvement and intellectual goals were ideals accessible to those with modest means. His early education took many turns: he started with law, shifted to geological studies at the Government School of Mines in 1861, and soon entered the brewing industry as an analytical chemist. This series of changes suggests a curious and eager mind rather than indecision.
In 1872, while managing a brewery, he bought a large reflecting telescope. This purchase marked the beginning of a focus that would shape his intellectual legacy. During a time when amateur science was both respectable and often fruitful in Britain, Knobel invested his own resources and free time into serious astronomical research. In 1875, he chose to learn Arabic and Persian to read medieval star catalogues in their original languages, which elevated him from a proficient amateur observer to a serious historian of astronomy.
