Woman of the Week: Hedy Lamarr (née Hedwig Eva Maria Kiesler)

How many inventors can lay claim to the title ‘the Most Beautiful Woman in Films?’ There’s just one who springs to mind, but such singularity is typical to Hedy Lamarr (1914-2000), the Austro-Hungarian film star who invented the basis of Wifi and Bluetooth in her free time. Gorgeous, successful and obviously ingenious, Hedy is the kind of role model the world should know about.

Hedy’s life was fascinating before she ever began to dabble in inventing. The daughter of Jewish-born parents, Hedy was born in Vienna, capital of the now obsolete Austro-Hungarian Empire. In the late 20’s, she trained as an actress in Berlin under theatre great Max Reinhardt. A year after appearing as an extra in her first film, Geld auf der Straße, she caused worldwide sensation by starring in 1933 film Extase, in which she not only appeared naked in numerous scenes, but even mimicked an orgasm onscreen – the first time a female actor had done so in a theatrically-released film.

After the attention garnered by her acting, at 19, Hedy married Friedrich Mandl, an Austrian military arms manufacturer and one of the richest men in the country. Her husband turned out to be a controlling pro-Fascist, and Hedy found herself practically imprisoned in her own luxurious home. It was there, though, that she first became familiar with weapons technology, as she attended dinners with her husband where conversation focused around new developments in armaments and artillery.

Opinions differ as to how she left her suffocating and morally compromising marriage. Hedy claimed to have drugged her maid to escape disguised in her clothes, but other sources suggest she simply disappeared during a dinner party to which she had worn as much expensive jewellery as possible. In either case, by 1937 she had met Louis B. Mayer in Paris and signed a contract with MGM studios, thus launching her Hollywood career. She chose her film name out of reverence for silent film star, the late Barbara La Marr.

Hedy’s smouldering good looks and the scent of scandal that surrounded her guaranteed her success in the flourishing film industry. She starred in various famous films over a period of 20 years, starting with Algiers in 1938 and including Boom Town (1940) with Clark Gable as leading man, White Cargo (1942) and Samson and Delilah (1949), which was at the time of its release the third highest-grossing film made.

Being frequently typecast as little more than a glamorous sex symbol with relatively few acting challenges, Hedy sought distraction in inventing, despite having no formal training. Horrified by the course of World War 2, she turned her inventing attentions to the war effort. Hedy realised the importance of radio-guided torpedoes but lamented how easily they could be disarmed by jamming the radio signal controlling them. To get around this, she proposed the idea of frequency-hopping: sending messages via multiple different frequencies, changing rapidly and semi-randomly from one to another so that it would be harder to block. If the control centre was synced to change to the same frequencies as the torpedo, the message would still be received perfectly clearly.

“Any girl can be glamorous. All you have to do is stand still and look stupid.” – Hedy Lamarr

Sharing her ideas with composer George Antheil, the pair used piano rolls as the foundations of the device that would actually allow this frequency-hopping, the earliest form of spread-spectrum communication. They patented their ‘Secret Communication System’ in 1942, and submitted the idea to the US Navy, who took little

notice of the civilians’ suggestion until 1962, when it was used during the Cuban missile crisis. Unfortunately, by this time, the patent had expired. The same patent is now recognised as the basis of the field of frequency-hopping, widely used not only in military communications but in all kinds of wireless transmission including Wifi, Bluetooth and CDMA (used in GPS and mobile phones).

Hedy and George’s impressive work finally began to find acknowledgement in 1997, with both of them receiving the American Electronic Frontier Foundation Pioneer award, prompting Hedy’s sardonic remark, ‘Well, it’s about time.’ A century after her birth, and 14 years after her death, Hedy was also posthumously inducted into the National Inventors Hall of Fame.

 

Woman of the Week: Ada Lovelace (née Augusta Ada Byron)

Ada in 1840 (by Alfred Edward Chalon)

Ada Lovelace (1815-1852) is known as the ‘mother of modern computing’, but not by nearly enough of the world. The only legitimate child of the famous poet, Lord Byron, she deserves fame in her own right for her contributions to computing and mathematics, a field vastly different from her father’s.

Ada never knew Lord Byron, thanks in part to his dying when she was just 8 years old, but more specifically due to her mother, Anne Isabella Milbanke, maintaining a violent dislike for her husband, who she considered insane. Hoping to discourage any similar tendencies in their only offspring, she encouraged Ada to study mathematics and science, which she believed would help subdue poetic (and thus insane) proclivities.

Whether due to her mother’s grooming or her own natural talent, Ada’s zest for innovation and learning manifested at an early age. When she was just 12, Ada was designing wings to allow human flight, using her anatomical observations of birds to determine the size, shape and materials that would best achieve her goal.

Her education was enhanced greatly by the opportunity of having Mary Somerville, one of the first known female scientists, as a tutor. Becoming close friends with the Scottish mathematician, it was Somerville who both encouraged her studies in higher mathematics and who would eventually introduce her to Charles Babbage in 1833. The 17 year old scholar quickly gained his respect and began an extensive correspondence with him in which they discussed mathematics and Babbage’s invention, an early calculator he called the difference machine. Babbage clearly respected his gifted protégée, coming to refer to her as the ‘Enchantress of Number’.

Ada shed her famous father’s name in 1835, upon marrying William King, later the first Earl of Lovelace. Fortunately, King appears to have supported her scholastic pursuits, and together the couple enjoyed the society of various known academics of the time including Michael Faraday and Charles Dickens. Family life didn’t prevent Ada’s continuing endeavours – in fact, her most famous contributions were made only after the birth of her third and last child.

In 1842, Ada started translating a French work describing Babbage’s newest computational concept, called Sketch of the Analytical Engine invented by Charles Babbage. However, the notes and algorithms that she added to the basic translation were so abundant that by the time it was published, the work was largely her own.

There remains contention regarding whether Ada herself wrote an algorithm intended to compute Bernouli numbers, widely considered to be the first known computer program. While it is certain that she worked on it, some scholars believe that the actual calculations were performed by Babbage, with Ada only editing it and specifically correcting a major error made by the older mathematician. Regardless of the exact details, it was remarkable work for the 26 year old that gives Ada and Babbage every right to their titles as the ‘mother and father’ of computer programming.  In addition, Ada is credited with being the first to recognise the wider application of using algorithms for any sort of information, such as music or language, by converting the data into numerical form. Today, this concept seems meaninglessly abstruse or glaringly self-evident: at the time, it was revolutionary.

“[The Analytical Engine] might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations…” – (notes on Sketch of the Analytical Engine invented by Charles Babbage, 1843)

Sadly, from 1843, Ada’s health declined and she began to drink heavily and rely on opiates prescribed as painkillers, causing her moods to be erratic. Her habit of gambling resulted in huge debts after she tried unsuccessfully to devise a mathematical model allowing for large wins, and this minor scandal was exacerbated by rumours of affairs with various men. She died tragically young in 1852, aged just 36, from uterine cancer.
