| - K. Eric Drexler was very strongly influenced by ideas on Limits to Growth in the early 1970s. His response in his first year at Massachusetts Institute of Technology was to seek out someone who was working on extraterrestrial resources. He found Dr. Gerard K. O'Neill of Princeton University, a physicist famous for a strong focus on particle accelerators and his landmark work on the concepts of space colonization. Drexler was involved in NASA summer studies in 1975 and 1976. Besides working summers for O'Neill building mass driver prototypes, he delivered papers at the first three Space Manufacturing conferences at Princeton. The 1977 and 1979 papers were co-authored with Keith Henson, and patents were issued on both subjects, vapor phase fabrication and space radiators. Drexler participated in NASA summer studies on space colonies in 1975 and 1976. He fabricated metal films a few tens of nanometers thick on a wax support to demonstrate the potentials of high performance solar sails. He was active in space politics, helping the L5 Society defeat the Moon Treaty in 1980. During the late 1970s, he began to develop ideas about molecular nanotechnology (MNT). In 1979, Drexler encountered Richard Feynman's provocative 1959 talk There's Plenty of Room at the Bottom. The term nanotechnology was coined by the Tokyo Science University Professor Norio Taniguchi in 1974 to describe the precision manufacture of materials with nanometer tolerances, and was unknowingly appropriated by Drexler in his 1986 book Engines of Creation: The Coming Era of Nanotechnology to describe what later became known as molecular nanotechnology (MNT). In that book, he proposed the idea of a nanoscale "assembler" which would be able to build a copy of itself and of other items of arbitrary complexity. He also first published the term "grey goo" to describe what might happen if a hypothetical self-replicating molecular nanotechnology went out of control. Drexler holds three degrees from MIT [1]. He received his S.B. in Interdisciplinary Sciences in 1977 and his S.M. in 1979 in Astro/Aerospace Engineering with a Master's thesis titled "Design of a High Performance Solar Sail System,." In 1991 he earned a Ph.D. under the auspices of the MIT Media Lab (formally, the Media Arts and Sciences Section, School of Architecture and Planning). His Ph.D. work was the first doctoral degree on the topic of molecular nanotechnology and (after some editing) his thesis, "Molecular Machinery and Manufacturing with Applications to Computation," was published as "Nanosystems: Molecular Machinery, Manufacturing and Computation" (1992), which received the Association of American Publishers award for Best Computer Science Book of 1992. Drexler and Christine Peterson, at that time husband and wife, founded the Foresight Institute in 1986 with the mission of "Preparing for nanotechnology.” Drexler and Peterson ended their 21-year marriage in 2002. Drexler is no longer a member of the Foresight Institute. In August 2005 Drexler joined Nanorex, a molecular engineering software company based in Bloomfield Hills, Michigan, to serve as the company's Chief Technical Advisor.[2][3] Nanorex's nanoENGINEER-1 software was reportedly able to simulate a hypothetical differential gear design in "a snap". According to Nanorex's web site, an open source molecular design program is currently slated for release in Fall 2007. In 2006, Drexler married Rosa Wang, a former investment banker who works with Ashoka: Innovators for the Public on improving the social capital markets.
