CELEBRITY FOCUS

James Earl Jones

Actor James Earl Jones, a Broadway, television and movie star, was well-known for his voice as Darth Vader in Star Wars and his book Voices and Silences. Jones spoke some of the most memorable lines in the history of American film, but the man known for his voice was once afflicted with a severe stutter.

Bruce Willis

While the world knows Bruce Willis as an A-list actor, few know that he struggled with stuttering throughout his first 20 years.

Walter Bruce Willis was born in 1955 in West Germany to his German mother, Marlene, and his American GI father, David Willis. The family settled in David’s hometown of Penns Grove, New Jersey in 1957, and the couple has three other children.

Byron Pitts

Byron Pitts has brought much attention to stuttering with his memoir, Step Out on Nothing: How Faith and Family Helped Me Conquer Life’s Challenges, released in September, 2009. The book not only details his speech difficulties, but also his illiteracy until age 12 and his unstable family life. Pitts overcame the odds to become the chief national correspondent with ABC News.

Lewis Carroll

The recent Disney version of Lewis Carroll’s classic, Alice in Wonderland, garnered a great deal of media hype. Even though the mainstream media has not made mention that Carroll was a person who stuttered, his family history gives credence to the discovery of the genetic link to stuttering. Carroll was born to parents who were first cousins; almost all of their eleven children, three girls and seven boys, struggled with stuttering past childhood.

Winston Churchill

Seeking to "remove Winston Churchill's stutter by second guessing the diagnosis" indicates neither a truthful retelling of history nor an informed opinion about a complex speech disorder, say experts in the field of speech-language pathology.

Recent news reports that quote Dr. John Mather, a Washington physician, as saying that Churchill's stutter "is a lie" brought adamant critical response from specialists in the field of stuttering and fluency disorders.
