In this week’s installment of our ongoing series bringing you the history of Princeton University and its faculty, students, and alumni, a member of the original House of Nassau visits campus, emails about Hillary Clinton clog inboxes, and more.

April 21, 1920—The Daily Princetonian reports on a new fashion trend: “Blue denim has at last made its appearance on the campus” thanks to “a courageous band of undergraduates.” Despite this, jeans will not be considered generally acceptable student attire for decades.

April 22, 1982—Queen Beatrix of the Netherlands, a member of the House of Nassau for which Nassau Hall is named, speaks in McCosh Courtyard as part of a celebration of the 200th anniversary of the establishment of diplomatic relations between Holland and the United States.

April 23, 1861—56 students are excused from their academic programs and leave campus “in consequence of the state of the country.” After the Civil War, Southern students will continue to avoid Princeton for the most part until the turn of the following century.

April 24, 1997—Students emailed the news that they will be unable to get tickets to First Lady Hillary Clinton’s keynote address at the first annual Symposium on New Jersey Issues begin hitting “reply all” to the list of more than 1,112 email addresses to express their feelings, a new experience for most. After several days of clogging inboxes with around 300 messages per day, they will be threatened with disciplinary action if they do not stop mass-emailing their classmates. The Daily Princetonian describes the original 66-kilobyte message as “mammoth” and reports that the incident risks “damage to the University computing system.”
