Grenfell cloth was named after Sir Wilfred Thomason Grenfell, a doctor who pioneered a medical mission in one of the world’s bleakest and most inhospitable outposts along the Labrador coast of Newfoundland.
Grenfell cloth was developed especially for sir Wilfred by a Mr Walter Haythornthwaite, a mill owner in Lancashire in the 1920’s, and whose name still graces the company that sells Grenfell Coats, Haythornthwaite & Sons Ltd.
Sir Wilfred talked in a hall t Burnley, Lancashire, about what was required in cloth for artic clothing:
“The right cloth for Labrador mission workers should be light…strong…weatherproof…and windproof. Above all it must allow body moisture to escape.”
