Sheila Michaels, the American feminist who brought the honorific 'Ms' into mainstream use, died aged 78.
The term wasn't invented by her; it was "arcane knowledge", but she popularized it.
Unlike the conventional "Mrs" or "Miss", it didn't convey a woman's marital status.
Ms Michaels chanced upon it as she was "looking for a title for a woman who didn't 'belong' to a man".

'Ms' caught her attention when she saw it on an address on a magazine being home-delivered; she first thought it was a typo.
