Muriel Bristol

[2] One day at Rothamsted, Ronald Fisher offered Bristol a cup of hot tea that he had just drawn from an urn.

Bristol declined it, saying that she preferred the flavour when the milk was poured into the cup before the tea.

"[3] Fisher and Roach hastily put together an experiment to test Bristol's ability to identify the order in which the two liquids were poured into several cups.

[3] He developed Fisher's exact test to assess the probabilities and statistical significance of experiments.

She studied botany and completed a PhD on algae at Birmingham, under the tutelage of George Stephen West.
