Western blotting is named after the technique's inventor, Dr. Edwin Southern, who developed the method in the 1970s. It is a play on the name of another technique called "Southern blotting," named after Dr. Edwin Southern himself. The term "Western" was chosen to differentiate this technique from Southern blotting and Northern blotting, which were named after the direction of transfer of DNA or RNA fragments.
