Walter Butler Cheadle (October 1836, Colne, Lancashire – 22 March 1910, London) was an English paediatrician.
[1] He interrupted his studies in 1861 to join Lord Milton on an expedition to explore Western Canada (1862–1864), and then on to China.
Arriving in Quebec City in July 1862, they travelled across the continent, wintering near Fort Carlton.
On returning home, with Milton, he co-authored a book on their adventures, The North-West Passage by Land (London, 1865), which described their expedition in considerable detail, which gained a lot of attention.
Cheadle published the first observation on acute rachitis after J. O. L. Möller, calling the disease infantile scurvy.
