Biography

Lieberfarb was born to a Jewish family, the son of a children's clothing manufacturer. He graduated with a B.S. in economics from The Wharton School at the University of Pennsylvania and a M.B.A. from the University of Michigan. In 1967, he worked as a financial analyst for Paramount Pictures where he was introduced to the concept of films on a disc and was asked by then president Stanley R. Jaffe to research new home video technologies. In 1973, he took a job as vice president for telecommunications at 20th Century Fox. In 1984, he accepted a job as president of Warner Home Video (WHV), the home entertainment arm of Warner Bros. Entertainment, where he guided the company through nearly two decades of growth. Lieberfarb's most significant achievement at WHV was his widely acknowledged role as the architect of the DVD. He has been called “The Father of DVD” by Variety, Home Media Magazine and Media Play News. It was his initial vision that evolved into today's DVD, the format that revolutionized the home video business model from rental to purchase, driving unprecedented growth in studio home video revenues. In January 2003, James F. Cardwell was appointed his successor at WHV and Lieberfarb founded Warren N. Lieberfarb & Associates, LLC. Lieberfarb currently serves on the board of directors of Hughes Telematics, Inc. (HUTC.OB). He has served as a member of the board of directors of Sirius Satellite Radio and thePlatform (since 2006 a subsidiary of Comcast Interactive Media). He also served on the University of Pennsylvania’s Board of Trustees, and served on the Library Board of Overseers and the Undergraduate Advisory Board of The Wharton School. Lieberfarb also served on the board of directors and Board of Trustees of the American Film Institute.

Personal life From 1987 to 1990, Lieberfarb was in a relationship with Faye Dunaway. He is married to investment adviser Gail Kamer. The couple lives in Brentwood, Los Angeles.

Worked examples

Example 1 — a first encounter with Warren Lieberfarb

Start with the simplest possible case. Write down what Warren Lieberfarb claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Warren Lieberfarb before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Warren Lieberfarb ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Warren Lieberfarb

In research: Warren Lieberfarb appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Warren Lieberfarb in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Warren Lieberfarb is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, 20th-century American Jews, 21st-century American Jews, so understanding it makes those chapters shorter.
In everyday life: Look for Warren Lieberfarb outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
