In this vein, Bell was an advocate of forced sterilization and was closely connected with the eugenics movement in the United States.
In , he presented data to the National Academy of Sciences indicating that congenitally deaf parents were more likely to produce deaf children and tentatively suggested that deaf people should not be allowed to marry each other.
He also conducted sheep-breeding experiments at his estate to see if he could increase the numbers of twin and triplet births. In , he hastily constructed a metal detector as a way to try and locate a bullet lodged in President James Garfield after an assassination attempt.
He would later improve this and produce a device called a telephone probe, which would make a telephone receiver click when it touched metal. And when Bell's newborn son, Edward, died from respiratory problems, he responded by designing a metal vacuum jacket that would facilitate breathing.
The apparatus was a forerunner of the iron lung used in the s to aid polio victims. Other ideas he dabbled in included inventing the audiometer to detect minor hearing problems and conducting experiments with energy recycling and alternative fuels.
Bell decided that a promising approach was to use an induction balance, a by-product of his research on canceling out electrical interference on telephone wires.
Bell determined that a properly configured induction balance would emit a tone when a metal object was brought into proximity with it. Surgeons adopted it, and it was credited with saving lives during the Boer War — and World War I — In September the Bell family vacationed in Nova Scotia, Canada, and immediately fell in love with the climate and landscape.

Throughout his life, Bell sought to foster the advance of scientific knowledge. He supported the journal Science , which later became the official publication of the American Association for the Advancement of Science.
He was one of the founders of the National Geographic Society in and succeeded his father-in-law, Gardiner Hubbard, as president of the society between and In that year his son-in-law, Gilbert H.
