Olinger migrated to the United States in 1871 and came directly to Dubuque. After eighteen months as a farm hand, he moved to the city and began a livery business that he maintained for fifteen years. In 1877 he also opened a saloon and grocery store on the corner of Clay and 17th Street. (1)
In 1891 Olinger sold his livery business but retained his interest in buying and selling horses. (2) He owned the celebrated horse "Keno F."
