Lindblad Expeditions Holdings, Inc.
A pioneer of modern expedition cruising, it sails ships to remote places like Antarctica and the Galápagos and runs land-based adventure tours under brands such as Natural Habitat and Classic Journeys. Swedish-American Lars-Eric Lindblad founded the line and led the first civilian expedition to Antarctica in 1966, earning him the nickname "father of eco-tourism." Its National Geographic partnership, born in 2004, grew partly out of his son Sven-Olof's boyhood idolization of the magazine.
