A marine biologist and professional naturalist, Jack Stein Grove has spent much of the past two decades traveling on, photographing and lecturing about, the world's oceans. The adventurous lifestyle of this 20th-century naturalist is reflected in Jack's travel schedule. Since his first expedition to Antarctica in 1985, he has participated in at least 20 expeditions to the southernmost continent during the Austral summer and has led numerous expeditions to the Galápagos where he lived for seven years. He has served as lecturer with Jean-Michael Cousteau aboard the Royal Viking Queen on a series of voyages from Cocos Island around South America to the Falklands; and as expedition leader along the west coast of South America from Guayaquil, Ecuador, to Puerto Mont, Chile. He also participated as marine naturalist aboard an expedition to the Weddell Sea by Russian icebreaker.

Jack is an avid scuba diver and dive master, certified by the Professional Association of Dive Instructors and has served as dive master aboard the world's greatest expedition ships in most of the seas on our planet.

As a research associate in the Section of Fishes at the Los Angeles County Museum of Natural History (LACM), Jack has become a leading authority on the fishes and marine environments of the Galápagos Islands. During the years he lived in the Galápagos he carried out marine biological studies on behalf of the Ecuadorian National Fisheries Institute and the LACM. In 1997 Stanford University Press published Jack's volume on The Fishes of the Galápagos, which represents the culmination of 20 years of research. A comprehensive work richly illustrated, the book includes details on 444 species of this incredible archipelago. He is also the author of a wide variety of scientific and popular articles. In 2003 the Charles Darwin Foundation nominated Jack to serve on its General Assembly.
