Wikipedia:Articles for deletion/Ernst Julius Amberg
The notability guidelines for academics are more aimed at the present day than at mathematicians of the late 18th and early 19th century. And we do have one in-depth source on the subject http://www-history.mcs.st-andrews.ac.uk/Biographies/Amberg.html. If we had a second source, independent of that one and more in-depth than https://www.genealogy.math.ndsu.nodak.edu/id.php?id=9700, I think he'd pass . He doesn't appear to be significant except as a teacher of Einstein, but significance is different than notability
