S. L. (Stephen Lincoln) Goodale

Born in 1815 and active in Maine, Stephen Lincoln Goodale wrote about agriculture for working farmers as well as for wider public audiences. Records gathered here link him to books and lectures including The Principles of Breeding (1861), which explored the laws of reproduction and the improvement of domestic animals, and a later lecture on commercial manures delivered before the Farmers' Convention in Augusta in 1869.

The surviving bibliographic trail suggests that agriculture was the center of his life's work. A memorial address published in 1898, shortly after his death in 1897, was titled Stephen Lincoln Goodale. His life work in behalf of Maine agriculture, which strongly suggests the regard he earned in that field.

I couldn't confirm many personal details beyond his dates and his agricultural writing, so this picture remains focused on the part of his life that is clearly documented: helping bring practical and scientific ideas into 19th-century farming.
