Hedy Lamarr

Hedy Lamarr was born Hedwig Eva Maria Kiesler on November 9, 1914, in Vienna, then part of Austria-Hungary. She was the only child of Emil Kiesler, a successful bank director, and Gertrud Kiesler, a pianist. Growing up in an intellectually stimulating household, she developed a fascination with both the arts and technology. Her father often explained how machines and mechanical

devices worked during their walks together, encouraging a curiosity that would remain with her throughout her life. Lamarr attended private schools in Vienna and received a good education, although she did not pursue higher education. As a teenager she became interested in acting, studying drama and quickly finding work in the European film industry.

Her early fame came from the controversial 1933 Czech film Ecstasy, which attracted international attention because of its artistic treatment of sexuality and helped establish her as one of Europe’s most talked-about young actresses. Her personal life changed dramatically when she married Austrian munitions manufacturer Fritz Mandl in 1933.

The marriage was unhappy and restrictive, but it exposed her to discussions of military technology, weapons systems, and communications equipment. After escaping the marriage in the late 1930s, she made her way to London, where she met film producer Louis B. Mayer of MGM. Mayer signed her to a Hollywood contract and gave her the name Hedy Lamarr. Arriving in the United States in 1938,

she quickly became one of Hollywood’s most glamorous stars. Throughout the 1940s she appeared in a succession of successful films including Algiers, Boom Town, Ziegfeld Girl, White Cargo, H.M. Pulham, Esq., and Samson and Delilah. Her striking beauty earned her worldwide fame, and she was frequently promoted as one of

the most beautiful women in the world. Although she often expressed frustration at being typecast as a glamorous leading lady, she remained a major box-office attraction during Hollywood’s Golden Age. In addition to her film work, Lamarr made occasional appearances on radio programs, including dramatic anthologies and entertainment broadcasts that were popular during the era. Like many Hollywood stars of the 1930s and 1940s,

she used radio as a means of promoting films and reaching audiences beyond movie theaters. While radio never became the primary focus of her career, her appearances helped maintain her public profile during the height of her fame. Away from the cameras, Lamarr devoted considerable time to inventing. Despite having no formal engineering training, she was an enthusiastic and gifted self-taught inventor. During World War II she became

concerned about the vulnerability of radio-controlled torpedoes to enemy jamming. Working with avant-garde composer George Antheil, she developed a frequency-hopping communications system designed to allow signals to switch rapidly among different frequencies. The pair received U.S. Patent No. 2,292,387 in 1942 for their “Secret Communication System.”

legal disputes, and a retreat from public life. Despite periods of financial and personal difficulty, interest in her achievements as an inventor grew steadily during the final decades of her life. Recognition for Lamarr’s inventive work came relatively late. In 1997 she and George Antheil received the Pioneer Award from the Electronic Frontier Foundation in acknowledgment of their contribution to communications technology.

James, Denise, and Anthony, as well as grandchildren and other family members. Today, Lamarr is remembered not only as one of the defining screen stars of classic Hollywood but also as an inventive thinker whose work helped earn her a place in the history of modern communications technology.
