The Kratt Brothers

Martin (born December 23, 1965) and Chris Kratt (born July 19, 1969) are American zoologists, educational nature show hosts, wildlife filmmakers and YouTubers. Sons of musical instrument manufacturer William King "Bill" Kratt, the brothers grew up in Warren Township, New Jersey and together created the children's television series Kratts' Creatures, Zoboomafoo, Be the Creature (which aired on the National Geographic Channel and CBC), and Wild Kratts (which airs on PBS Kids and TVOKids).

Martin was born on December 23, 1965, and Chris was born on July 19, 1969, in New Jersey to Linda (born 1939) and William Kratt (1928–2022). They are the grandsons of musical instrument maker William Jacob Kratt (1892–1983), who emigrated from Germany to America in 1910.

The brothers attended Watchung Hills Regional High School. Both were inducted into the school's hall of fame in 2013. Martin holds a Bachelor of Science in zoology from Duke University, and Chris holds a Bachelor of Arts in biology from Carleton College.

Shortly after graduating from Duke University, Martin became a research assistant for a howler monkey project under Dr. Kenneth Glander in Costa Rica. Shortly after, he worked with Dr. Patricia Wright in Madagascar as well as Dr. John Terbogh in the Peruvian Amazon rainforest. In 1990, Chris served as an intern at Conservation International in Washington, D.C. A year later, he started the Carleton Organization for Biodiversity. His ecology studies have been funded by the Explorers Club and the National Science Foundation. He was also the recipient of the Thomas J. Watson Fellowship.
