Werner Hans Erhard (born John Paul Rosenberg, September 5, 1935) is an author of transformational models and applications for individuals, groups, and organizations. He is currently writing about integrity, performance and leadership and has lectured at (among others) Harvard, Yale,USC, the University of Rochester and Rotterdam School of Management

Erhard was first known for "The est Training" (1971–1983) and "The Forum" (1984–1991), which were offered to the public through an organizational structure that included Erhard Seminars Training Inc. (1971–1975), est, an educational corporation (1975–1981), and Werner Erhard & Associates (WEA, 1981–1991). Erhard, along with John Denver, Robert W. Fuller, and others, founded The Hunger Project in 1977.

In 1991, Erhard retired from business, sold his then-existing intellectual property to a group of his former employees (who formed Landmark Education) and moved abroad.

John Paul Rosenberg was born in Philadelphia, Pennsylvania on September 5, 1935. His father was a small restaurant owner who left Judaism for a Baptist mission before joining his wife in the Episcopal Church where she taught Sunday School. They agreed that their son should choose his religion for himself when he was old enough. He chose to be baptized in the Episcopal Church, served there for eight years as an acolyte and has been an Episcopalian ever since.

Richard Buckminster "Bucky" Fuller (July 12, 1895 – July 1, 1983) was an American systems theorist, architect, engineer, author, designer, inventor, and futurist.

Fuller published more than 30 books, inventing and popularizing terms such as "Spaceship Earth", ephemeralization, and synergetic. He also developed numerous inventions, mainly architectural designs, the best known of which is the geodesic dome. Carbon molecules known as fullerenes were later named by scientists for their resemblance to geodesic spheres.

Fuller was born on July 12, 1895, in Milton, Massachusetts, the son of Richard Buckminster Fuller and Caroline Wolcott Andrews, and also the grandnephew of the American Transcendentalist Margaret Fuller. He attended Froebelian Kindergarten. Spending much of his youth on Bear Island, in Penobscot Bay off the coast of Maine, he had trouble with geometry, being unable to understand the abstraction necessary to imagine that a chalk dot on the blackboard represented a mathematical point, or that an imperfectly drawn line with an arrow on the end was meant to stretch off to infinity. He often made items from materials he brought home from the woods, and sometimes made his own tools. He experimented with designing a new apparatus for human propulsion of small boats.

Henry John Deutschendorf, Jr. (December 31, 1943 – October 12, 1997), known professionally as John Denver, was an American singer/songwriter, activist, and humanitarian. After traveling and living in numerous locations while growing up in his military family, Denver began his music career in folk music groups in the late 1960s. His greatest commercial success was as a solo singer. Throughout his life Denver recorded and released approximately 300 songs, about 200 of which he composed. He performed primarily with an acoustic guitar and sang about his joy in nature, his enthusiasm for music, and relationship trials. Denver's music appeared on a variety of charts including country & western, the Billboard Hot 100, and adult contemporary, in all earning him 12 gold and 4 platinum albums with his signature songs "Sunshine on My Shoulders", "Take Me Home, Country Roads", "Leaving on a Jet Plane", "Rocky Mountain High", "Annie's Song", and "Calypso".

Denver further starred in films and several notable television specials in the 1970s and 1980s. In the following decades he continued to record, but also focused on calling attention to environmental issues, lent his vocal support to space exploration, and testified in front of Congress to protest censorship in music. He is known for his love of the state of Colorado, which he sang about numerous times. He lived in Aspen, Colorado, for much of his life, and influenced the governor to name him Poet Laureate of the state in 1974. The Colorado state legislature also adopted "Rocky Mountain High" as one of its state songs in 2007. He was an avid pilot, and died while flying his personal aircraft at the age of 53. Denver was one of the most popular acoustic artists of the 1970s.

Warren Gamaliel Bennis (born March 8, 1925) is an American scholar, organizational consultant and author, widely regarded as a pioneer of the contemporary field of Leadership studies. Bennis is University Professor and Distinguished Professor of Business Administration and Founding Chairman of The Leadership Institute at the University of Southern California.

"His work at MIT in the 1960s on group behavior foreshadowed -- and helped bring about -- today's headlong plunge into less hierarchical, more democratic and adaptive institutions, private and public," management expert Tom Peters wrote in 1993 in the foreword to Bennis’ An Invented Life: Reflections on Leadership and Change.

Management expert James O'Toole, in a 2005 issue of Compass, published by Harvard University's John F. Kennedy School of Government, claimed that Bennis developed "an interest in a then-nonexistent field that he would ultimately make his own -- leadership -- with the publication of his 'Revisionist Theory of Leadership' in Harvard Business Review in 1961." O'Toole observed that Bennis challenged the prevailing wisdom by showing that humanistic, democratic-style leaders are better suited to dealing with the complexity and change that characterize the leadership environment.
