Children: Antony Loder (b. 01 March 1947), Denise Loder (b. 29 May 1945), James (b. 06 March 1939 - father John Loder; adopted 16 October 1939 as James Markey Lamarr).
Dr. Kleiner's pet head-crab "Lamarr" in the computer game Half-Life 2 (2004) (VG) is named after her.
During her marriage to screenwriter Gene Markey, the two adopted a son, James. She soon after gave birth to two children, Denise Hedy and Antony, while married to actor John Loder.
For her appearance in Ecstasy (1933), Hedy is credited as being the first nude woman as well as portraying the first sex-scene in film history. Scenes were cut and additional ones added in order to be able to release it in some countries. However, she was actually at least 18 years too late to be the first nude woman in film, as both Inspiration (1915) and Lois Weber's Hypocrites (1915) had beaten her to it.
Hedy's credited invention was for a radio guiding system for torpedoes which was used in WWII. She supposedly gained the knowledge from her first husband, Fritz Mandl, a Viennese munitions dealer who sided with the Nazis. Hedy drugged her maid to escape her husband and homeland.
Her profile was the most requested in the 1940s by women to their plastic surgeons.

Took her, then new, stage name (Lamarr) in memory of Barbara La Marr, the silent screen star.
Was cast in the picture Picture Mommy Dead (1966), but fired on February 3, 1966, when she didn't show up for the first day of shooting.
Was co-inventor (with composer George Antheil) of the earliest known form of the telecommunications method known as "frequency hopping", which used a piano roll to change between 88 frequencies and was intended to make radio-guided torpedoes harder for enemies to detect or to jam. The method received U.S. patent number 2,292,387 on Aug. 11, 1942, under the name "Secret Communications System". Frequency hopping is now widely used in cellular phones and other modern technology. However neither she nor Antheil profited from this fact, because their patents were allowed to expire decades before the modern wireless boom. She received an award from the Electronic Frontier Foundation in 1997 for her pioneering work in spread-spectrum technology.
