This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand William B. Lenoir rather than just read about it. In short: William Benjamin Lenoir (March 14, 1939 – August 26, 2010) was an American electrical engineer and NASA astronaut. Early life and education William Benjamin Lenoir was born on March 14, 1939, in Miami, Florida, as a son of Samuel Staples Lenoir (1910–1989) and Iona Catherine Lenoir (née Yann; 1915–1977).

Key takeaways

  • William B. Lenoir belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect William B. Lenoir to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of William B. Lenoir from memory before moving on to harder problems.

Reference excerpt

William Benjamin Lenoir (March 14, 1939 – August 26, 2010) was an American electrical engineer and NASA astronaut.

Early life and education William Benjamin Lenoir was born on March 14, 1939, in Miami, Florida, as a son of Samuel Staples Lenoir (1910–1989) and Iona Catherine Lenoir (née Yann; 1915–1977). He attended Coral Gables Elementary School, Ponce de Leon Junior High School, and graduated from Coral Gables Senior High School in 1957. He graduated with a Bachelor of Science degree in electrical engineering from the Massachusetts Institute of Technology in 1961, where he was an active member of Sigma Alpha Epsilon (SAE). Lenoir continued at MIT, earning a Master of Science degree in 1962, and a Doctor of Philosophy degree in EECS in 1965. While working for his doctoral degree, Lenoir received an award for excelling at teaching undergraduate courses. From 1964 to 1965, Lenoir was an instructor at MIT; and in 1965, he was named associate professor of electrical engineering. His work at MIT included teaching electromagnetic theory and systems theory, as well as performing research in remote sensing. He was an investigator in several satellite experiments and continued research in this area while fulfilling his astronaut assignments.

NASA career Lenoir was working on Apollo Applications experiments at MIT when he saw an advertisement in a science magazine recruiting NASA astronauts. He sent in an application and was selected as a scientist-astronaut by NASA in August 1967. He completed the initial academic training and a 53-week course in flight training at Laughlin Air Force Base, Texas. He received his wings with distinguished graduate honors in April 1969. Lenoir was backup science pilot for Skylab 3 and Skylab 4, the second and third crewed missions in the Skylab program. During Skylab 4, he was co-leader of the visual observations project and coordinator between the flight crew and the principal investigators for the solar science experiments. From September 1974 to July 1976, Lenoir spent approximately one-half of his time as leader of the NASA Satellite Power Team. This team was formed to investigate the potential of large-scale satellite power systems for terrestrial utility consumption and to make program recommendations to NASA Headquarters. Lenoir supported the Space Shuttle program in the areas of orbit operations, training, extravehicular activity, and payload deployment and retrieval. Lenoir flew as a mission specialist on STS-5 (November 11–16, 1982), the first Space Shuttle flight to deploy commercial satellites, and logged over 122 hours in space. Following STS-5, Lenoir was responsible for the direction and management of mission development within the Astronaut Office. Lenoir resigned from NASA in September 1984, to assume a position with the management and technology consulting firm of Booz Allen Hamilton in Arlington, Virginia. He returned to NASA in June 1989 as the Associate Administrator for Space Flight, responsible for the development, operating and implementation of the necessary policy for the Space Shuttle and all U.S. government civil launch activities. Lenoir resigned from NASA again in April 1992, to become vice president of the Applied Systems Division at Booz Allen Hamilton in Bethesda, Maryland.

Spaceflight experience

STS-5 launched from Kennedy Space Center, Florida, on November 11, 1982. This was the first operational flight of the Space Shuttle Columbia and became known as the "We Deliver" mission. Two commercial communications satellites with Payload Assist Module upper stages (PAM-D) were successfully deployed from the Orbiter's cargo bay, a new first. This activity was shared with the world when the onboard television tape was played to the control center later that evening. In addition to collecting precise data to document the Shuttle's performance during launch, boost, orbit, atmospheric entry and landing phases, STS-5 carried a Getaway Special experiment, three Student Involvement Project experiments, and medical experiments. STS-5 was the last flight to carry the Development Flight Instrumentation (DFI) package to support flight testing. Lenoir and Allen were to perform a spacewalk, the first of the Shuttle program, to test newly developed space suits. The space suits were developed as cheaper and less complicated alternatives to the Apollo versions. The test was delayed by one day due to Lenoir succumbing to motion sickness. Then an underperforming oxygen regulator in Lenoir's suit caused them to cancel the extravehicular activity (EVA) entirely. It was the first time in the history of the space program that an EVA had been cancelled due to space suit issues. The STS-5 crew successfully concluded the 5-day orbital flight of Columbia with the first entry and landing through a cloud deck to a hard-surface runway, demonstrating maximum braking. STS-5 completed 81 orbits of the Earth before landing at Edwards Air Force Base, California, on November 16, 1982.

Personal life Lenoir was married twice. He had three children. Lenoir logged over 3,000 hours of flying time in jet aircraft.

Death Lenoir died August 26, 2010, after suffering head injuries during a bicycle accident near his home in Sandoval County, New Mexico.

Organizations Lenoir was a senior member of the Institute of Electrical and Electronics Engineers, and a member of the American Institute of Aeronautics and Astronautics, Eta Kappa Nu and the Society of Sigma Xi.

Honors and awards Lenoir received a number of honors. He was a Sloan Scholar at the Massachusetts Institute of Technology, winner of the Carleton E. Tucker Award for Teaching Excellence at MIT, and recipient of the NASA Exceptional Service Medal (1974) and NASA Space Flight Medal (1982).

Worked examples

Example 1 — a first encounter with William B. Lenoir

Start with the simplest possible case. Write down what William B. Lenoir claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to William B. Lenoir before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about William B. Lenoir ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of William B. Lenoir

In research
William B. Lenoir appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses William B. Lenoir in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
William B. Lenoir is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1939 births, 1982 in spaceflight, 2010 deaths, so understanding it makes those chapters shorter.
In everyday life
Look for William B. Lenoir outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
