The outermost sections of Hitchcock (Sections I & V) house primarily upper-class students. They have small hallways with six to eight residents per floor, many in single rooms. Section I is the farthest from the front desk of Hitchcock and each floor is mixed-sex with a shared bathroom. It has some of the largest rooms in Hitchcock Hall, and includes several rooms known as "octagons" which are located in a turret-like structure and have many windows overlooking 57th and Ellis. The basement entrance to this section opens up into the common area that connects Snell and Hitchcock. Section I also contains "horseshoe doubles" (room #1x7), large doubles with separate niches and closets for each resident. The horseshoe doubles also have a (nonworking) fireplace and large hearth. Section I was also home to noted astronomer, Emmy award winner, and Pulitzer and Hugo award-winning author Carl Sagan in the 1954–1955 academic year.
