Purdue University, located in West Lafayette, Indiana, U.S., is the flagship university of the six-campus Purdue University system. Purdue was founded on May 6, 1869, as a land-grant university when the Indiana General Assembly, taking advantage of the Morrill Act, accepted a donation of land and money from Lafayette businessman John Purdue to establish a college of science, technology, and agriculture in his name. The first classes were held on September 16, 1874, with six instructors and 39 students. Today, Purdue enrolls the second largest student body of any university in Indiana as well as the second largest international student population of any public university in the United States.

Purdue offers both undergraduate and graduate programs in over 210 major areas of study, and is well known for its competitive engineering curricula. The university has also been highly influential in America's history of aviation, having established the first college credit offered in flight training, the first four-year bachelor's degree in aviation, and the first university airport (Purdue University Airport). In the mid-20th century, Purdue's aviation program expanded to encompass advanced spaceflight technology giving rise to Purdue's nickname, Cradle of Astronauts. Twenty-two Purdue graduates have gone on to become astronauts, including Gus Grissom (one of the original Mercury Seven astronauts), Neil Armstrong (the first person to walk on the moon), and Eugene Cernan (the most recent person to walk on the moon).

Reuben Lucius Goldberg (July 4, 1883 – December 7, 1970) was an American cartoonist, sculptor, author, engineer and inventor.

He is best known for a series of popular cartoons depicting complex gadgets that perform simple tasks in indirect, convoluted ways. These devices, now known as Rube Goldberg machines, are similar to those drawn by W. Heath Robinson in the UK and Storm P in Denmark^{[citation needed]}. Goldberg received many honors in his lifetime, including a Pulitzer Prize for his political cartooning in 1948 and the Banshees' Silver Lady Award 1959.

Goldberg was a founding member and the first president of the National Cartoonists Society, and he is the namesake of the Reuben Award, which the organization awards to the Cartoonist of the Year. He is the inspiration for various international competitions, known as Rube Goldberg Machine Contests, which challenge participants to make a complex machine to perform a simple task.

Winter guard is an indoor color guard activity, derived from Military Ceremonies or Veterans Organizations Ceremonies Unlike traditional color guard, winter guard is performed indoors, usually in a gymnasium or an indoor arena. Performances make use of recorded music rather than a live band or orchestra.

Winter guard ensembles commonly perform at judged competitions officiated by local and regional associations using criteria developed by Winter Guard International.

A winter guard generally consists of performing members under the direction of an instructional staff. The staff of a winter guard team ("the guard") are drawn from many different specialties, which sometimes overlap: there are equipment instructors (sometimes one for the unit, sometimes broken out into the individual sections), dance instructors, and drill instructors. The equipment instructors create the choreography performed with equipment and teach it to the guard. The dance instructors create and teach the movement choreography in the show. The drill instructors focus on the position of the guard members relative to one another and to the boundaries of the performance area, in addition to where each member goes at which specific time during the performance. In some cases, all of these roles are fulfilled by one sole director.
