Leonard (Lenny) Lipton (born May 18, 1940, Brooklyn, New York) is an author, filmmaker and inventor. At age 19, Lipton wrote the poem that became the basis for the lyrics to the song "Puff the Magic Dragon". He went on to write books on independent filmmaking and become a pioneer in the field of projected three-dimensional imagery. His technology is used to show 3D films on more than 25,000 theater screens worldwide.


Lipton majored in physics at Cornell University after starting out in electrical engineering. A self-described "mediocre student", he only excelled once he found a field he loved. Lipton now urges schools to be more "accepting of eccentric people with a different point of view because we are the people who make the difference."


Puff the Magic Dragon

Lipton was 19 when he wrote the poem that was adopted into the lyrics for the 1963 song "Puff the Magic Dragon", performed by Peter Paul and Mary. His inspiration was a 1936 Ogden Nash poem, "A Tale of Custard the Dragon". "Pirates and dragons, back then, were common interests in stories for boys," Lipton said. "The Puff story is really just a lot like Peter Pan.” Lipton has spent years denying that the song was about marijuana and believes that the myth was created by New York columnist Dorothy Kilgallen.

Independent films

In the 1960s, Lipton shot several experimental films on 16 mm stock, most with running times of less than 10 minutes. The best known, Let a Thousand Parks Bloom, a 27-minute film about Berkeley's People's Park, played in the at the Tate Liverpool Museum and the Whitney Museum of American Art. The following decade, he wrote two books on technologies and methods for independent filmmakers: The Super 8 Book (1975) and Independent Film Making (1979). Lipton on Filmmaking, a compendium of his magazine writings, was also published in 1979.


Lipton is a pioneer in the field of projected three-dimensional imagery and is one of the creators of the electronic stereoscopic display industry. His interest dates back to his childhood in New York where he attended movie palaces, with some films shown in 3D. He drew his own 3D comics using red and green crayons on tracing paper, which were viewed using primitive glasses constructed of cardboard tubes and magnifying lenses.

Royalties from "Puff the Magic Dragon" and Independent Filmmaking, which remained in print for 20 years, gave Lipton an independent income that allowed him to follow his interests. His career in stereoscopic display began to gel around 1972. In one early stint, he served as the "convergence setter" for the 1983 3D film Rottweiler: Dogs from Hell, determining for each shot the optimal distance separating the two camera lenses. Previewing a scene from the film, technical staff from Universal were impressed by the stereoscopic imagery, but little else.

He built a prototype of a flicker-free, field-sequential 3D display system and founded StereoGraphics Corporation in 1980 to fund development. The system worked by doubling the display rate of images, thereby overcoming a problem inherent in 3D motion picture projection, where each eye views only half the available images. In 1989, he patented the active ZScreen polarization filter which uses a circularly polarized liquid crystal filter placed in front of a projector, which can then display both the left and right halves of a stereo pair. After Real D Cinema acquired StereoGraphics in 2005, the technology became the basis for the RealD cinema system. As of 2017, the system was in use in more than 26,500 screens worldwide. Lipton was the chief technology officer at RealD until 2009, when he left to do independent consulting.

Lipton published his definitive treatment of the subject, Foundations of the Stereoscopic Cinema: A Study in Depth, in 1982. In 2011, the International 3D Society gave him its Century Award for Lifetime Achievement. As of 2015, he held 68 stereography-related patents.

Entrevista a Litto Nebbia (I)

por Manel Gausachs el 15/10/2018

Litto Nebbia actuó el pasado 18 de mayo en Barcelona dentro de una pequeña gira española de cuatro conciertos en pequeños locales. Aprovechamos la ocasión para hablar con él poco antes de cumplir los 70. En esta primera entrega de la entrevista, que publicamos en dos partes, hablamos con detalle de seis de los siete discos que ha publicado en estos últimos tres años. Seis obras de géneros muy diferentes que demuestran, una vez más, que Nebbia trasciende los límites del Rock y del relato juvenil que se le adjudicó en sus inicios. En la segunda entrega, que publicaremos próximamente, hablaremos de su faceta como productor, de su nueva autobiografía Mi banda sonora y de lo cerca y lejos que está a la vez entre sí todo el mundo hispánico de la música.
