Humphrey Belcher was a wizard who believed that a cheese cauldron was a good idea. Albus Dumbledore would later comment that he had been "woefully wrong" in this belief. Belcher could have been an inventor of a cauldron constructed from cheese.
"Humphrey" means "peaceful warrior" from the Germanic elements hun "warrior, bear cub" and frid "peace". The Normans introduced this name to England, where it replaced the Old English cognate Hunfrið, and it was regularly used through the Middle Ages.
Humphrey Belcher was the name of a real person living in the United Kingdom, b. 1545, Lavenham, Suffolk County, England. The family had descendants in Northhamptonshire also. Humphrey is the oldest documented Belcher with that surname's spelling. A "Belchere" was a man of good heart (French Bel = good Cher = dear) - basically the king's agent and provider of rations, munitions, water, stables and lodgings when the king travelled throughout Britain. The real Humphrey Belcher's descendants included Jonathan Belcher, who sailed from the USA to England and back again, and was an early Governor of New Jersey, and New Hampshire setting up the institutin later known as Princeton University - where there is a "Belcher Hall" to this day.
