Sawdust inventor

Dr Sylvester Graham, the famous sawdust inventor, died at Northampton, Mass., on the 10th inst., aged fifty years.
Liberty (Mo.) Weekly Tribune, October 24, 1851, p. 1.

Sylvester Graham is credited with being the first to recognize that, in America at least, there's a market for dietary answers to physical problems. Funny that a newspaper with two entire pages out of its total four full of advertisements, including plenty for surefire remedies peddled by one "doctor" or another, would revert to snark in announcing someone's death.

Incidentally, that abbreviation "inst." was common enough.
Inst. = instant = within the same month.
Ult. = ultimo = last month.
