Le Corbusier developed the Modulor in the long tradition of Vitruvius, Leonardo da Vinci's Vitruvian Man, the work of Leone Battista Alberti, and other attempts to discover mathematical proportions in the human body and then to use that knowledge to improve both the appearance and function of architecture. The system is based on human measurements, the double unit, the Fibonacci numbers, and the golden ratio. Le Corbusier described it as a "range of harmonious measurements to suit the human scale, universally applicable to architecture and to mechanical things."
Le Corbusier published Le Modulor in 1948, followed by Modulor 2 in 1955. These works were first published in English as The Modulor in 1954 and Modulor 2 (Let the User Speak Next) in 1958.
Le Corbusier used his Modulor scale in the design of many buildings, including Notre Dame du Haute and buildings in Chandigarh. In the construction of the first Unité d'Habitation apartment building, in Marseilles, a version was cast in concrete near the entrance.The graphic representation of the Modulor is a stylized human figure with one arm upraised stands next to two vertical measurements, the red series based on the figure's navel height (108cm in the original version, 1.13m in the revised version) then segmented according to Phi, and the blue series based on the figure's entire height, double the navel height (216cm in the original version, 2.26m in the revised), and likewise segmented. A spiral, graphically developed between the red and blue segments, seems to mimic the volume of the human figure.

At SPACEHAB, in Titusville, Fla., STS-101 crew members take part in a Crew Equipment Interface Test (CEIT). Here they are checking out the SPACEHAB Logistics Double Module. The crew is composed of Commander James Donald Halsell Jr., Pilot Scott J. "Doc" Horowitz (Ph.D.), and Mission Specialists Mary Ellen Weber (Ph.D.), Edward Tsang Lu (Ph.D.), Jeffrey N. Williams, and Yuri Malenchenko and Boris W. Morukov, who are with the Russian Space Agency. The primary objective of the STS-101 mission is to complete the initial outfitting of the International Space Station, making it fully ready for the first long-term crew. The seven-member crew will transfer almost two tons of equipment and supplies from SPACEHAB. Additionally, they will unpack a shipment of supplies delivered earlier by a Russian Progress space tug and begin outfitting the newly arrived Zvezda Service Module. Three astronauts will perform two space walks to transfer and install parts of the Russian Strela cargo boom that are attached to SPACEHAB's Integrated Cargo Container, connect utility cables between Zarya and Zvezda, and install a magnetometer/pole assembly on the Service Module. Additional activities for the STS-101 astronauts include working with the Space Experiment Module (SEM-06) and the Mission to America's Remarkable Schools (MARS), two educational initiatives. STS-101 is scheduled for launch no earlier than March 16, 2000. Image from NASA, originally appeared on this site: science.ksc.nasa.gov/gallery/photos/ Reposted by San Diego Air and Space Museum
Soyuz TM-14 descent module, 1992
This spacecraft made the 14th flight to the Mir space station, and was the first Soyuz mission of the Russian Federation. TM craft were used to ferry three-man cosmonaut and astronaut teams to and from Mir and the International Space Station between 1986 and 2002. Soyuz is now the only way of sending cosmonauts and astronauts to the International Space Station.

Optional printer module. I still have 3 unopened ribbons of ink. It could also print without ink onto thermal paper, which is what you see here. The print would last for a couple of weeks before fading. I love that it had this dual functionality. You could decide if your print was important enough to use your ink for more permanence.
