The Greenwood Story

Inventions and new technologies were being introduced to the world
In 1879, while new inventions such as the first radio transmission, movie projector, and incandescent light bulb were being introduced to the world, Thomas Wotton Greenwood was a young budding engineer determined to change the ventilation industry. Over time, Thomas grew from a young apprentice to a business owner, and his company expanded from a small showroom to Queens Chambers in Deansgate and opened premises in 151 Edmund Street before eventually moving to 83 Colmore Row.
Greenwood was up and running!
By this time Thomas Greenwood had made a name for himself as a ventilating engineer. You can see one of the adverts published in 1884 which shows an array of ventilators.
