The Alexandre Yersin Museum is a modest but worthwhile stop for anyone curious about the man behind one of Nha Trang's most unusual historical threads. Yersin was a Swiss-French physician and bacteriologist associated with the discovery of the plague bacillus, but in Vietnam he was also an explorer, agricultural experimenter, and local institution.
The museum is small, with photographs, instruments, letters, and personal objects rather than spectacle. Its strength is context: after beaches and boat trips, it points to the scientific and colonial networks that connected Nha Trang with Dalat, Pasteur Institute research, and the wider history of medicine in Indochina.
