The 1960 presidential campaign of John F. Kennedy, a United States Senator from Massachusetts, began on January 2, 1960, when Kennedy formally announced his candidacy for 35th President of the United States, replacing incumbent President of the United States Dwight D. Eisenhower.
 Kennedy was nominated by the Democratic Party at the Democratic National Convention of 1960, taking place between July 11 and July 15, 1960.
 On July 15, 1960, Kennedy named Senator Lyndon B. Johnson of Texas as his official running mate.
 Kennedy and Johnson won the election on November 8, 1960, defeating incumbent Vice President and Republican nominee Richard Nixon, who would later go on to be the 37th President of the United States.
 Kennedy and Johnson were sworn in as 35th President and 37th Vice President of the United States on January 20, 1961 respectively.
 Kennedy would serve as President of the United States until his death in November 1963.
James Abram Garfield (November 19, 1831 – September 19, 1881) was the 20th President of the United States, serving from March 4, 1881, until his assassination later that year.

The history of The Baltimore City College began in March 1839, when the City Council of Baltimore, Maryland, United States, passed a resolution mandating the creation of a male high school with a focus on the study of English and classical literature.
 The Baltimore City College was opened later in the same year on October 20, with 46 pupils under the direction of Professor Nathan C. Brooks,(1809-1898), a local noted classical educator and poet, who became the first principal.
 It is now considered to be the third oldest public high school in the nation.
 In 1850, the Baltimore City Council granted the school the authority to present its graduates with certificates of completion.
 An effort to expand that academic power and allow the then named "Central High School of Baltimore" to confer Bachelor of Arts degrees began in 1865, and continued the following year with the renaming of the institution as "The Baltimore City College", which it still holds to this day, with also the retitling of its chief academic officer from "principal" to "president", along with an increase in the number of years of its course of study and the expansion of its courses.
 However, despite this early elevation effort, it ended at that time unsuccessfully in 1869, although the B.C.C. continued for a number of years as a hybrid public high school and early form of junior college (later known as community college) which did not fully appear in America until the beginning of the 20th century.
 Very often the graduation diploma in the late 19th and early 20th Centuries was accepted by many other colleges and universities entitling City graduates to enter upper-division schools at the sophomore year, (which was also coincidentally a privilege also accorded to its later local academic and athletic rival, the Baltimore Polytechnic Institute, founded 1883).
Juan Bautista Sacasa (León, Nicaragua, 21 December 1874 – Los Angeles, California, 17 April 1946) is the 20th President of Nicaragua from 1 January 1933 to 9 June 1936.
 He was the eldest son of Roberto Sacasa, 44th and 46th President of Nicaragua, and Ángela Sacasa Cuadra, the former's cousin twice removed.

 It was the location of James A. Garfield's assassination.
James A. Garfield, the 20th President of the United States, was assassinated at 9:30 am on July 2, 1881, less than four months into his term as President.
 He was shot by Charles J. Guiteau at the Baltimore and Potomac Railroad Station in Washington, D.C., and died in Elberon, New Jersey on September 19, 1881.
 Guiteau's motive was revenge against Garfield for an imagined political debt.
 Garfield was the second of four Presidents to be assassinated, following Abraham Lincoln and preceding William McKinley and John F. Kennedy.
 His Vice President, Chester A. Arthur, succeeded Garfield as President.
Theodore Roosevelt Jr. ( ; October 27, 1858 – January 6, 1919) was an American statesman, author, explorer, soldier, naturalist, and reformer who served as the 26th President of the United States from 1901 to 1909.
 He also served as the 25th Vice President of the United States from March to September 1901 and as the 33rd Governor of New York from 1899 to 1900.
 As a leader of the Republican Party during this time, he became a driving force for the Progressive Era in the United States in the early 20th century.
 His face is depicted on Mount Rushmore, alongside those of George Washington, Thomas Jefferson, and Abraham Lincoln.
Charles Julius Guiteau ( ; September 8, 1841June 30, 1882) was an American writer and lawyer who was convicted of the assassination of James A. Garfield, the 20th President of the United States.
 Guiteau was so offended by Garfield's rejections of his various job applications that he shot him at the Baltimore and Potomac Railroad Station in Washington, D.C. on July 2, 1881.
 Garfield died two months later from infections related to the injury.
 In January 1882, Guiteau was sentenced to death for the crime, and was hanged five months later.
