Early Life
On August 2, 1820, Tyndall was born in Leighlin Bridge, a small Irish town close to Carlow, where his father worked as a policeman. After completing some formal education, he worked as an engineer and surveyor to obtain experience in the field. -
Career
The Ordnance Survey of Ireland hired him as a surveyor. He was employed in Carlow, Youghal, and Kinsale before switching to the English survey and moving to Preston in 1842. He developed an interest in continuing his studies while there and started taking evening sessions at the neighborhood Mechanics Institute. -

Career Pt. 2
John received an opportunity to join the Royal Institution as a Professor of Natural Philosophy. After taking the job for two years, he had gained the respect of his peers in the scientific community. He lectured to the world's most elite and learned brains while working at the Royal Institution until his retirement. Over the course of his time at the institution, he rose through the ranks from professor to superintendent of the house to director of the laboratory. In 1887 Tyndall retired. -
Tyndall Effect
Through multiple internal reflections, he demonstrated how light propagates through a tube of water. He called this a light-pipe, which served as a precursor to modern optical fibres used in communication systems. In addition to his rigorous experimental approach, Tyndall developed optical methods for measuring particles that relied on the scattering of light (the Tyndall Effect). This allowed him to test purified air for purity and cleanliness using simple methods. -
Tyndallization
Three days in a succession, food is placed in a can or other heat-resistant storage container, which is then cooked for 15 to 20 minutes each day. It simply remains at ambient temperature on the counter the remainder of the time. This is to make sure that the bacteria gets killed (Jackson, 2020). -
Death
John Tyndall passed away at the age of 73 due to his wife accidentally killing him by giving him the wrong medication. Timetoast -
