About: James Ballantyne Hannay

An Entity of Type: person, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

James Ballantyne Hannay FRSE(1855–1931) was a Scottish chemist who believed he had synthesized diamond in 1880. However, modern testing showed that the surviving samples from his experiments were natural diamond, not synthetic. While his techniques were conducive to diamond formation, modern diamond production – not achieved until the 1950s – requires capabilities not available in Hannay's time. Hannay was also known for making precision instruments.
