Origins of Calcium
The pure form of calcium was found in 1808 by Sir Humphrey Davy. Other scientists were trying to get the form, but Sir Humphrey Davy did electrolysis with lime and carbon that created the calcium. The name calcium came from the latin word of lime, which was calx, since lime made the pure form.
