Henry How (11 July 1828 – 28 September 1879) was a British-Canadian chemist, geologist and mineralogist.

Career[]

In 1847, How and August Wilhelm von Hofmann were co-workers at the Royal College in London. How was a professor of chemistry and natural history at King's College in Windsor, Nova Scotia.

The mineral howlite is named for Henry How.

In 1864 How published the description of a new zeolite mineral, that he named mordenite, from along the shores of the Bay of Fundy.^[2] In 1868, he described a new borate mineral found just south of Windsor.^[3] How named it silicoborocalcite but was renamed howlite in his honor by James Dwight Dana.^[4] He studied many other zeolites and related minerals from the Bay of Fundy basalts, borates from the gypsum and anhydrite deposits, as well as ores of manganese and iron.

Personal life[]

How married Louisa Mary Watkins (11 May 1830 - 9 July 1910) and they had five children.^[1] The grave of one of their children is next to Henry How's and reads, Louisa P. Juliet, second child of Henry How and Louisa M. How, died 8 July 1862 aged 4 years and 6 months.^[5]
