Potter Palmer (May 20, 1826 – May 4, 1902) was an American businessman who was responsible for much of the development of State Street in Chicago. Born in New York City, Albany County, New York, he was the fourth son of Benjamin and Rebecca (Potter) Palmer.
Potter Palmer founded a dry goods store, Potter Palmer and Company, on Lake Street in Chicago in 1852. Unlike many stores of the time it focused on women and encouraged their patronage. Palmer instituted a "no questions asked" returns policy and allowed customers to take goods home to inspect before purchasing, which served to nurture the goodwill and patronage of Chicagoans. He made the store much larger and more distinctive than other stores of the time. Palmer was the first owner to advertise with large window displays that included price comparisons.
When Palmer's doctor urged him to get out of the business in 1865 because of ill health, he brought in partners Marshall Field and Levi Leiter. The trio joined forces and renamed the firm Field, Palmer, Leiter and Company. The store would eventually develop into the prominent Midwestern department store chain Marshall Field and Company.
In 1867, Palmer sold his share of the partnership and focused his efforts on his real estate interests, leasing a new building to his former partners in 1868 at State and Washington. He built several buildings along State Street on property he owned, including the Palmer House Hotel. When his buildings were destroyed in the Great Chicago Fire, Palmer borrowed $1.7 million to rebuild, the largest amount lent to a private individual up to that time. He reclaimed the swampland north of Chicago's commercial district, developing it into Lake Shore Drive.
In 1871, he married Bertha Honoré. In 1874 a son, Honoré, was born; in 1875, Potter Palmer II. Both went on to have sons named Potter Palmer III, as well as other children.
