Some picture accounts keep claiming that the design of Doctor Who’s Daleks was based on America’s first policewoman Sgt Alice Wells, appointed in 1910. Usually the claim contains this picture:

This is totally wrong:

1.  Original Dalek design was not based on any police outfit. Read How it all began. Or watch a video: Doctor Who – Raymond Cusick Visits the BBC Props Department and Studios. (YouTube).
   
2. That is not a photo of Sgt. Alice Wells, but a Suffragette posed to illustrate the woman police concept. (Mashable article).

You can read about Alice Stebbins Wells from Wikipedia.
