All over the world, new parents agonise over the names of newborn babies. They test out combinations of first and last names, nicknames and initials, anxious to avoid any mickey-taking potential.
But sometimes even the most sensible of names turns out to be not quite good enough.
Novelist Alison Potter's parents settled on a name she was happy with for 40 years. But then, as she recently wrote in The Guardian, on the verge of publishing her debut thriller Wink Murder, her publisher informed her that her name must be changed.
Pen names have long been used by novelists - think Mark Twain, George Orwell or Lewis Carroll - and the reasons are diverse. Privacy is a common justification, as is a desire to maintain some separation between one's writing and one's personal life. Louisa May Alcott may be known for her wholesome family novels, but she paid the bills by secretly writing racy thrillers, mysteries and romances for the more lucrative magazine market under the name A.M. Barnard.
Others have opted for pen names to avoid discrimination. Charlotte Bronte first published Jane Eyre under the masculine name Currer Bell, because she and her sisters Anne and Emily (also known as Acton and Ellis Bell) believed critics to be prejudiced against female authors. Even J.K. Rowling switched Joanne for gender-neutral initials because her publisher was concerned boys would not read books written by a woman.
