author
An old Philadelphia maker of human and animal remedies, this company also published practical farm booklets for poultry and livestock keepers in the late 19th and early 20th centuries.

by Pratt Food Company
Published as a corporate author rather than a single person, Pratt Food Company is best known today for practical guides such as Pratt poultry pointers and other advice books on horses, livestock, and poultry.
Available library and archive records identify the business as a Philadelphia company founded in 1872 that specialized in remedies for both humans and animals. Its surviving publications read like a mix of handbook, advertisement, and everyday farm advice, which helps place them in the world of small-scale agriculture and household animal care of their time.
Because this is a company name, not an individual author, there does not appear to be a standard personal biography or portrait to use here.
