Incompatible birth dates
Sources disagree: March 31, 1838 (Biographisch-literarisches Handwörterbuch zur Geschichte der exacten Wissenschaften) or in 1837 (Discovery of the Elements 7th edition).
The main date retains its own sources. These alternatives overlap neither all other statements nor the main date. Rank is Wikidata editorial priority, not proof.
