author
A late 19th-century writer and publisher, this author is best known for a practical guide to ferrets, rats, and rat extermination drawn from firsthand experience. The book mixes animal observation, pest-control advice, and the brisk, entrepreneurial energy of its time.
Writing under the name "Sure Pop," Adolph Isaacsen published All about Ferrets and Rats, a handbook that appeared in New York in the 1880s and 1890s. The book presents itself as a complete history of ferrets and rats, along with practical advice on rat extermination and the use of ferrets in pest control.
The surviving editions suggest he was not only the author but also the publisher of the work, with a business address at 92 Fulton Street in New York City. His writing leans on personal experience and study, giving the book a direct, hands-on feel rather than a purely academic one.
Although little biographical information seems to survive beyond his book and publishing record, Isaacsen remains an interesting figure from a time when animal care, urban pest control, and small-scale self-publishing could all meet in a single volume.
