b) Millard Fillmore

Millard Fillmore, who became U.S. President after Zachary Taylor’s death, is noted for modernizing the White House by installing its first library, kitchen stove, and bathtub. Fillmore’s presidency, which lasted from 1850 to 1853, was marked by efforts to maintain peace between the North and the South during a time of growing sectional tensions. Despite his contributions to the White House, Fillmore’s presidency is often overshadowed by his support for the Compromise of 1850 and the Fugitive Slave Act, which have marred his legacy. His tenure highlights the challenges of leadership in the lead-up to the American Civil War.
