Mary Aldis

Scientific author (1840?-1897)

Mary Aldis emigrated with her husband to New Zealand in 1884, when he was appointed as the first Professor of Mathematics at Auckland University College. Mary Aldis had already written an elementary arithmetic book The Giant Arithmos. In 1895 she published her most significant work, a 224-page illustrated volume on astronomy called Consider the Heavens.

Despite numerous biblical quotations it was a scientific work; comparing lunar craters with the extinct volcanoes around Auckland and citing spectroscopic data on Mars rather than more speculative ideas about Martians building canals.1

Aldis and her husband campaigned for higher education for women, and for moral purity. One Presbyterian minister commented at the time, "Mrs. Aldis, all the bad men in Auckland hate you."2 William Aldis had a contentious relationship with the College’s governing council and in 1893 he was dismissed. The couple returned to Britain in 1897 and Mary Aldis died that year.
