The English name of Coca-Cola was named by Pemberton’s assistant and partner at the time, accountant Robinson. Robinson was a classical calligrapher. He thought "two capital Cs would look great," so he wrote "Coca-Cola" in Spencerian cursive. "Coca" is a spice extracted from the leaves of the cocoa tree, and "cola" is an ingredient extracted from the cocoa fruit. The "Coca-Cola" trademark has remained unchanged for more than 100 years.
