Whonamedit?

Whonamedit? was an online English-language dictionary of medical eponyms and the people associated with their identification.^[1] Though it was a dictionary, many eponyms and persons are presented in extensive articles with comprehensive bibliographies.^[1] The dictionary was hosted in Norway and was developed by medical historian Ole Daniel Enersen.^[2]

As of June 2025 the Whonamedit web site appears to have gone offline, probably because Ole Daniel Enersen died in 2024. The site remains accessible through the Internet Archive.
