William Cruickshank (chemist)
From Wikipedia, the free encyclopedia
William Cruickshank (died 1810 or 1811) was a Scottish military surgeon and chemist, professor of chemistry at the Royal Military Academy, Woolwich.
Some authors credit Cruikshank with first suspecting an unknown substance in a Scottish mineral, strontianate, found near Strontian, in Argyleshire. Other authors name Adair Crawford for the discovery of this new earth due to the mineral's property of imparting a redding color to a flame[1]. It was later isolated by Humphry Davy and is now known as strontium.
In 1802, Cruikshank improved the construction of Alessandro Volta's voltaic pile, by arranging the plates horizontally in a trough rather than vertically in a column. [2]
