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.

In 1864 How published the description of a new zeolite mineral, that he named mordenite, from along the shores of the Bay of Fundy.{{cite journal|last1=How|first1=Henry|title=On Mordenite, a New Mineral from the Trap of Nova Scotia|journal=Quarterly Journal of the Chemical Society|date=1863|pages=100–104|url=http://rruff.info/uploads/JCS17_100.pdf}}
In 1868, he described a new borate mineral found just south of Windsor.{{cite journal|last1=How|first1=Henry|title=II. Contributions to the mineralogy of Nova Scotia. III.

Personal life
How married Louisa Mary Watkins (11 May 1830 - 9 July 1910) and they had five children. 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.Headstone
