Romanowsky staining is a prototypical
staining technique that was the forerunner of several distinct but similar methods, including
Giemsa,
Jenner,
Wright,
Field, and
Leishman stains, which are used to differentiate
cells in
pathologic specimens. It was named after the Russian physician Dmitri Leonidovich Romanowsky (1861–1921), who invented it in 1891.
