Born in 1908, Armorel studied Natural Sciences (Zoology) at LMH from 1926, graduating with a first class degree in 1930. She was tragically killed in a motor accident later that year. The Brown Book for December 1930 records that "She was a radiant person of rare vitality and joyousness. The work in which she delighted has lost a scholar of prominence and power. Her friends have lost a beautiful and sympathetic companion."
The Heron-Allen Science Scholarship were founded by her parents Edward and Edith Heron-Allen in memory of their daughter. The Scholarship, founded in 1936, was an award given to an undergraduate who intended to read Zoology or Physiology or, if no suitable candidate was found, Natural Science at the College. The scholarship is still awarded today to students reading Life Science or Mathematics. The trust also funds travel awards and an annual lecture.
