Chester A. Arthur was the 21st President of the United States, serving from 1881 to 1885. He was a Republican and a former lawyer who became known for his strong support of civil service reform. During his presidency, he signed the Pendleton Civil Service Act, which established a merit-based system for federal appointments and helped to reduce political corruption. Arthur also advocated for the protection of Native American rights and supported the creation of the United States Forest Service. Despite his accomplishments, Arthur's presidency was cut short by his untimely death from complications related to Bright's disease, a kidney condition.
