Pen Name/Pseudonym/Nom de Plume

 I thought you might find these little facts about pen names interesting.

 

Pseudonym/Nom de Plume/Pen Name

The three Bronte sisters began writing in an age (Victorian) when women writers were not taken seriously. In order to be judged on their work alone, they published as Currer, Ellis, and Acton Bell.

Each keeping their own initials.

Currer Bell—Charlotte Bronte

Ellis Bell—Emily Bronte

Acton Bell—Anne Bronte

It is thought that they took idea for the name Bell from a curate named Mr Bell-Nicholls who had come to Haworth to work for their father. Later, he married Charlotte, so Bell did indeed become part of her name.  

Also:

Instead of a pseudonym, Jane Austen merely stated 'By a Lady' on the cover of her novels. Though eventually she became well known by her own name. So much so, that the Prince Regent (Prinny) invited her to dedicate her novel Emma to him.
