Ludwig Grünwald (10 February 1863, Vienna – 11 August 1927) was an Austrian born, German internist and otolaryngologist.

He studied medicine in Munich, where after graduation, he opened a practice in internal medicine. He became a specialist in the field of otorhinolaryngology, being credited as the first physician to attempt surgery for the treatment of nasal suppuration and disease associated with the ethmoid and sphenoid bones.^[1]

Along with internist Richard May (1863-1936), he developed a solution that later became known as the May–Grünwald stain, a stain used for peripheral blood film and bone marrow.^[1] His books on diseases of the larynx and on nasal suppuration have been translated into English.^[2][3]

Aside from otolaryngology, he is also remembered for his discovery of a large ecchymosis located in the umbilicus associated with acute pancreatitis, the Grünwald's sign.
