Helen Charlotte Elizabeth Ogston later Townroe and then Bullimore (1882 – 1973) was a Scottish suffragette known for interrupting David Lloyd George on 5 December 1908 at a meeting in the Royal Albert Hall and subsequently holding off the stewards with a dog whip.

[2] Helen obtained a science degree at the University of Aberdeen before moving south with her younger sister, Constance.

As a result of the demonstration women were stopped from attending future talks by Lloyd George.

[4] Ogston noted her rationale for using the whip: "a man put the lighted end of his cigar on my wrist; another struck me in the chest.

"[6][7]Ogston was working for the WSPU in Brighton in 1909 and speaking on their behalf in the south of England, but she became a paid organiser for the New Constitutional Society for Women's Suffrage in 1910.
