In 1959, Swedish engineer Nils Bohlin, who had previously designed aircraft ejection seats, developed the three-point seat belt for Volvo. Easy to buckle with one hand, it restrains both the pelvis and the chest. Rather than keep it exclusive, the carmaker let all others use the design freely. It is estimated to have saved hundreds of thousands of lives worldwide.
In 1843, inventor Alexander Bain patented a way to send images over telegraph wires using synchronized pendulums. By the 1860s, a commercial fax service was already linking cities. The telephone wasn't patented until 1876, more than three decades after that first fax patent. The fax is really a child of the telegraph age.
On 8 October 1958, in Stockholm, 43-year-old Arne Larsson received the very first implanted pacemaker. The device, designed by engineer Rune Elmqvist and implanted by surgeon Åke Senning, worked for only a few hours and had to be replaced. Larsson went on to receive more than twenty pacemakers in his lifetime. He died in 2001 aged 86, outliving both the engineer and the surgeon.
