Invent By Refining Old Ideas

Can you take an old idea further to create a new invention?

To relieve pain, doctors in ancient Greece often prescribed a tea made from the leaves and bark of willow trees. In 1828, French scientist Henri Leroux isolated salicin, the ingredient in willow that relieved the pain.

In 1853, Charles Gerhardt, working with Leroux’s early studies, developed a new salicin compound that reduced existing side effects. In 1890, a German Scientist, Felix Hofmann, an employee of the Bayer Company, isolated the pain reliever in salicin and it was marketed as Aspirin.
