1. Tyndalisation

While Louis Pateur found a way to sterilise milk, John Tyndall also worked on this process which was called Tyndalisation. He refined and extended Pasteur’s work.

2. Light Pipe
Tyndall’s light pipe was a box filled with water. It had a tap at one end and a spout at the other. Tyndall shone a light on the water, the stream had trapped the light within itself. From these experiments we have fibre optics and and a gastroscope today.

3. The Telephone
While he didn’t invent the telephone, John Tyndall knew all about it. When he was lecturing in America he met with Aexander Graham Bell who told him about his invention. When he went back to England he set up a telephone and spoke to his assistant in Hyde Park while he was lecturing in the Royal Institution.

4. Mountaineer
In 1849 John Tyndall first visited the Alps. In 1856 he studied the movement in glaciers. Victorian England frowned on mountain climbing because it was dangerous. John Tyndall was the first to climb the Weisshorn and climbed Mont Blanc several times. In 1863 he would have been the first to climb Matterhorn, but his guides refused to go up to the last peak.
