Charles John Aldrich (1861-1908) American neurologist. Provided early description of Mees lines he termed 'Leuconychia striata arsenicalis transversus'
Mees lines: white bands traversing the full width of the nail, running parallel to the lunula, with no palpable ridges. As the nail grows they bands move distally and finally disappear when trimmed. The finding was initially related to acute arsenic poisoning.
