In the old days (and even the not-so-old days), every famous person was privately pushing science, technology, and the battle against Hitler forward: http://goo.gl/htfK0d
  1. Hedy Lamarr: WiFi Inventor
    Before today’s Google Doogle came along, why weren't we celebrating Hedy Lamarr as a 1940s version of Steve Jobs? While walking down red carpets and simulating onscreen orgasms by day, Lamarr was working in her laboratory by night. Her creations include a fluorescent dog collar and modifications to the Concorde, but most notably, she invented a torpedo guidance system that would actually go on to become the basis of all our wireless communications today.
  2. Neil Young: Train Master
    Neil’s son Ben loves model trains, and struggled to control them due to his cerebral palsy. So the guy behind ‘Harvest’ strapped on his train engineer's hat and invented a whole new remote control system called the Trainmaster Command Control, a programmable system that would reduce complex train maneuvers to something Ben could control with the tap of a button.
  3. Zeppo Marx: Heart Fixer
    Incredibly mechanically inclined for a comedian, Zeppo spent his post-movie days inventing things like what he catchily termed the cardiac pulse rate monitor. It was kind of like one of James Bond's high-tech gadgets, if James Bond had a severe cholesterol problem. It had two clock faces, one of which told the actual time, while the other one took note of your heart rate. If your pulse started doing a slapstick routine in your chest, the watch would pick it up and an alarm would sound.
  4. Wonder Woman's Creator: The Lie Detector's Creator
    More specifically, William Marston developed the version of the test that measures blood pressure. The connection between blood pressure and lying had already been explored in some detail in the late 19th century, but Marston was the first person to actually try building a way to measure it. Though, at this stage, the lie detector was not in lasso form.
  5. Romance Novelist Barbara Cartland: Aviation Pioneer
    Between writing her first book in 1922 and her death in 2000, Cartland had written 723 romance novels, making her one of the most prolific authors of all time. She also had a personal interest in gliding, and she was so proficient that she designed a glider that could be towed by an airplane, which she then flew in for over 200 miles over the south coast of England. The British military used her design to spruce up their defenses, and gliders were instrumental scouts for the D-Day operation.
