Architects: Hellmuth, Obata and Kassabaum furnish Building Section & Penthouse Details on Sheet A6 of the blueprints. With information from the prints and suggestions of Mr. Chih-Chen Jen, we explore the shape of the Planetarium's hyperboloid of one sheet exterior. The more recent modifications for the sky dome, exhibit areas and entrance areas were read from blueprint sheets A5.2 and A6.1, June 2000, provided by Mr. Thomas H. Teasdale, Associate Architect with Saur & Associates. Thomas Teasdale met with some math field trip classes during the construction period after 2000.

This material is presented in tribute to Mr. Chih-Chen Jen, Mr. Albert Alpers, Mr. Milo Ketchum, and Mr. Thomas Teasdale. You may link to the following pages:
