1859 John Francis Queeny was born in Chicago, Illinois, the eldest of five children, where he learned the value of hard work from his parents.
The Queeny family was doing well in Chicago until 1871 — the year of the Great Chicago Fire. As a twelve year-old boy, John Francis simply could not afford the luxury of continuing his education.
After several months of searching for a job in the fire-ravaged city of Chicago, he entered the chemical business as an office boy with the drug firm of Tolman and King earning $2.50 per week. John Francis Queeny quickly advanced to become a delivery boy.
1891 Queeny continued to work up the ranks and in 1891, went to St. Louis as an employee of the Meyer Brothers Drug Company. Shortly after that Mr. Queeny married Miss Olga Mendez Monsanto.
