Who invented the compressed air drill in 1887?

The compressed air drill, invented in 1887, is attributed to Germain Sommeiller. This invention was significant in the field of engineering and construction, particularly for its application in tunneling through solid rock. The use of compressed air to power the drill allowed for much greater efficiency and effectiveness compared to previous methods, such as hand drilling or steam power. Sommeiller's innovation marked a major advancement in excavation techniques and greatly facilitated the expansion of infrastructure projects, including railroads and tunnels.

The other individuals listed made substantial contributions in their respective fields—Theodore Maiman was known for developing the first working laser, Eli Whitney is famous for inventing the cotton gin and contributing to the concept of interchangeable parts in manufacturing, and Jack Kilby created the integrated circuit—however, none of them were involved in the invention of the compressed air drill, solidifying Sommeiller's place in engineering history.
