The story of the word

The Scottish surgeon Alexander Ogston named it in 1882 after looking down a microscope at pus from an abscess and seeing what he described as bunches of grapes. Streptococcus got its name the same way, from στρεπτός, twisted, because those cells form chains instead. The naming convention is purely visual: shape first, disease later.
