National Training Laboratories

Kurt Lewin founded the National Training Laboratories Institute for Applied Behavioral Science, known as the NTL Institute, an American non-profit behavioral psychology center, in 1947. NTL became a major influence in modern corporate training programs, and in particular developed the T-Group methodology that remains in place today. Lewin died early on in the project, which was continued by co-founders Ron Lippitt, Lee Bradford, and Ken Benne, among others. The NTL Institute produced or influenced other notable and influential contributors to the human relations movement in post-World War II management thought, notably Douglas McGregor (who, like Lewin, also died young), Chris Argyris and Warren Bennis.
