Firsts from President Hayes?

Well im doing a report on Rutherford B. Hayes, the 19th president of the U.S., and one of my main points is his firsts. So far i have that he was the first to be inaugurated inside the white house and the first to sign a bill that gave female attorneys the right to argue cases for the supreme court. any ideas? im only in the 7th grade, make sure your information is accurate!
