Seymour Liebergot is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Seymour Liebergot rather than just read about it. In short: Seymour "Sy" Abraham Liebergot (born February 15, 1936) is a retired NASA flight controller, serving during the Apollo program. Liebergot was an EECOM controller and was responsible for the electrical and environmental systems on board the Command Module.

Key takeaways

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

Reference excerpt

Seymour "Sy" Abraham Liebergot (born February 15, 1936) is a retired NASA flight controller, serving during the Apollo program. Liebergot was an EECOM controller and was responsible for the electrical and environmental systems on board the Command Module. In 1970, he was part of the team that guided Apollo 13 back to Earth following the explosion that crippled the spacecraft. He began his career in 1963 with North American Aviation after graduating from California State University, Los Angeles. In 1964, he came to NASA. Liebergot was an Assistant Flight Director on Apollo 4, then an EECOM flight controller on Apollo 8–15. On Apollo 17, he served as CSSB SPAN (SPacecraft ANalysis room) Support. He continued as a controller in the Skylab and ASTP missions.

Early life Seymour "Sy" Abraham Liebergot was born on February 15, 1936, in Camden, New Jersey, the second child of parents Ida née Soloff and Solomon "Sol" Liebergot. His paternal grandparents immigrated from Kyiv, Ukraine, and his maternal grandparents immigrated from Novosibkov, Russia to the U.S. Sy experienced an unstable and rough childhood. Though money was scarce, his father gambled, drank, and had many gangster friends and enemies. Ida spiraled into a nervous breakdown when Sol had an affair, attempting to kill Sy and his sister Phyllis in 1942. Ida was permanently institutionalized. Sol married the woman he had an affair with, and they later bore three more children. Sol constantly uprooted his family, moving from place to place in order to escape danger from his debts, and he neglected his family and often beat Sy.

Career

Early work After graduating high school in 1953, Liebergot worked as a copy boy at the Philadelphia Inquirer. In 1954, after turning 18, he decided to join the Army to take some time to receive technical training and figure out his life plans. He was stationed in Fort Huachuca and the Yuma Test Station, where he fulfilled weather activity duties. Sy was honorably discharged in 1957. That same year, he moved to Los Angeles, and married his first wife, Deanna Cohen. He decided to attend college for Electrical Engineering and enrolled at the Los Angeles City Junior College (LACC) for his first two years of study. He simultaneously worked as a shoe salesman for five years to support himself and his family. Liebergot’s first daughter, Shelli Lyn was born in 1958 and his twin sons, Mark Daniel and Scot Alan, were born in 1960. He graduated from LACC after five semesters and enrolled in California State University at Los Angeles (CSLA) to finish the last two years of his degree. Liebergot later moved to Houston to work for NASA.

Worked examples

Example 1 — a first encounter with Seymour Liebergot

Start with the simplest possible case. Write down what Seymour Liebergot claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Seymour Liebergot 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 Seymour Liebergot 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 Seymour Liebergot

In research: Seymour Liebergot appears in astronomy 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 Seymour Liebergot 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: Seymour Liebergot is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1936 births, 20th-century American Jews, 21st-century American Jews, so understanding it makes those chapters shorter.
In everyday life: Look for Seymour Liebergot 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.
