1. The scientist and discipline that I chose are engineering and Meredith C. Gourdine. Meredith was responsible for a technique called Incineraid that removes smoke from buildings.
2. Lonnie Johnson invented the super soaker
A.C Richardson invented the insect destroyer gun
Granville T. Woods invented the roller coaster
3. I chose Jan Ernst Matzeliger and he invented the shoe lasting machine. This machine connected the upper part of the shoe to the sole which was done by hand. This machine changed the shoe making industry because it allowed more shoes to be made.
