Salter

A manufacturer or dealer in salt. Someone who salts bodies in embalming.

"The old brick salt-warehouses clustered at the upper end of the city [New Orleans] looked as they had always looked: warehouses which had had a kind of Aladdin's lamp experience, however, since I had seen them; for when the war broke out the proprietor went to bed one night leaving them packed with thousands of sacks of vulgar salt, worth a couple of dollars a sack, and got up in the morning and found his mountain of salt turned into a mountain of gold, so to speak, so suddenly and to so dizzy a height had the war news sent up the price of the article."

Mark Twain, Life on the Mississippi (1883).
