The U.S. House of Representatives votes 11 articles of impeachment against President Andrew Johnson, nine of which cite Johnson’s removal of Secretary of War Edwin M. Stanton, a violation of the Tenure of Office Act. The House vote made President Johnson the first president to be impeached in U.S. history.

For the first time in U.S. history, the impeachment trial of an American president gets underway in the U.S. Senate.

The Patent No. 77,494 granted to Jones three years after the Civil War for her “Improvement to the Corn Husker, Sheller” was for a device that pulled off and cut up the corn husk and stripped the kernels off the cob, all at the same time, a key technological step in automating agricultural progress.

On May 16, 1868, the U.S. Senate votes against impeaching President Andrew Johnson for “high crimes and misdemeanors.” He would not be fully acquitted of all charges until 10 days later, on May 26, 1868.

At the end of a historic two-month trial, the U.S. Senate narrowly fails to convict President Andrew Johnson of the impeachment charges levied against him by the House of Representatives three months earlier. The senators voted 35 guilty and 19 not guilty on the second article of impeachment, a charge related to his violation of the Tenure of Office Act in the previous year. Ten days earlier, the Senate had likewise failed to convict Johnson on another article of impeachment, the 11th, voting an identical 35 for conviction and 19 for acquittal. Because both votes fell short–by one vote–of the two-thirds majority needed to convict Johnson, he was judged not guilty and remained in office.

By proclamation of General John A.
