(Karl) Ludwig Rütimeyer (born February 26, 1825 in Biglen, Canton of Bern; died November 25, 1895 in Basel) was a Swiss zoologist, anatomist and paleontologist, who is considered one of the fathers of zooarchaeology.
Rütimeyer studied at the University of Bern. He began his studies in theology before switching to medicine. Additional studies in Paris, London, and Leyden were in natural science. Ultimately, he got a habilitation from Bern, becoming the professor of zoology and comparative anatomy at the University of Basel. An area of specialization was the extinct fauna of Switzerland. Another area was the history of various mammalian species. His work in zooarchaeology included a report in 1861 about the remains of fish and domesticated animals from Swiss palafitte settlements.
