A method for detecting specific DNA sequences in samples by separating DNA fragments through gel electrophoresis, transferring them to a membrane, and hybridizing with labeled probes. It's used to identify gene presence, copy number, and structural variations.
Named after its inventor Edwin Southern at Edinburgh University in 1975, making it one of the few techniques named after a person rather than its function. Southern chose to name it after himself, establishing the precedent for the later compass-direction naming of related blotting techniques.
This is the only major molecular biology technique actually named after a person's real name - Edwin Southern! All the other 'directional' blots (Northern, Western) were just jokes playing off his surname, making Southern blot the accidental patriarch of a whole family of techniques.
Edwin Southern developed this technique (1975). The eponym convention in molecular biology heavily favored naming discoveries after male researchers, marginalizing contemporaneous female scientists' parallel work.
Credit the technique by function or acknowledge Edwin Southern's contribution while noting parallel work by female researchers.

Concurrent DNA mapping work by female geneticists was overshadowed by the Southern blot's commercial prominence and masculine-coded naming convention.
