About Eric Tigerstedt
- Eric Magnus Campbell Tigerstedt (August 14, 1887 – April 20, 1925) was one of the most significant inventors in Finland at the beginning of the 20th century and has been called the "Thomas Edison of Finland".
- He was a pioneer of sound-on-film technology and made significant improvements to the amplification capacity of the vacuum valve.
- Having seen a showing of the Lumière brothers' new motion picture technology as a 9-year-old boy in Helsinki in 1896, he was inspired to bring sound to silent pictures. Many years later, in 1914, his demonstration film Word and Picture was presented to a gathering of scientific dignitaries in Berlin, but his invention was never commercialised.
- In addition to improving the triode vacuum valve, he developed directional loudspeakers.
- Tigerstedt also predicted such future inventions as television and the mobile phone, and in 1917 he filed a patent for what he described as a "pocket-size folding telephone with a very thin carbon microphone".
- Tigerstedt was awarded a total of 71 patents in several countries between the years 1912 and 1924.
