Etymology of "Objectivism"

Does anyone know how, and why Ayn Rand’s philosophy came to be known as “Objectivism?”

Rand initially resisted naming her philosphy but was pressed too come up with a name. Another factor was that people started calling it Randism or refered to people as Randists. She hated that and thought such a name missed the entire point of her philosophy so she named it Objectivism because she beleived in Objective reality.
