Samuel Feltman

Samuel Feltman is a engineering 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 Samuel Feltman rather than just read about it. In short: Samuel Feltman (May 4, 1899 – September 6, 1951) was an American computer scientist and expert in weaponry. At the time of his death, Feltman was Associate Chief of the Research and Materials Branch and Chief of the Ballistic Section of the U.S.

Key takeaways

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

Reference excerpt

Samuel Feltman (May 4, 1899 – September 6, 1951) was an American computer scientist and expert in weaponry. At the time of his death, Feltman was Associate Chief of the Research and Materials Branch and Chief of the Ballistic Section of the U.S. Army Ordnance Research and Development Division. Feltman was centrally involved in the development of the first electronic computer, ENIAC, of the hypersonic wind tunnel, and of "Atomic Annie", the first nuclear artillery shell. Feltman proposed the ballistic characteristics of such weapons as the 90mm and 120mm antiaircraft guns, the 8‑inch gun, the 240mm howitzer, and many other weapons. In 1944, he was awarded the Decoration for Exceptional Civilian Service, the highest award given by the Army to a civilian. In honor of his service and contributions, the Picatinny Arsenal dedicated a building in his name, "The Samuel Feltman Ammunition Laboratory," Picatinny Arsenal, Dover, New Jersey. Feltman was born and raised in Long Branch, New Jersey, the son of Russian Jews. He joined the Army Ordnance Corps at the Sandy Hook Proving Ground in 1918, and served at the Aberdeen Proving Ground in Maryland. He also spent time serving as "what amounted to the permanent under-chief of the ballistics work in Washington" (D.C.). Feltman was killed at the age of 52 in an auto accident, along with his wife and father-in-law.

Development of the computer In 1946, John Mauchly and J. Presper Eckert developed the first electronic computer at the University of Pennsylvania. The funding for this computer, called ENIAC (Electrical Numerical Integrator And Calculator), was provided by the Ballistics and Ordnance Division of the U.S. Army. Lieutenant Herman Goldstine was the Army Officer most directly involved in the development of ENIAC. In his memoir/history of the development of the computer, Goldstine quotes his superior officer, Colonel Paul Gillon, who attributes a crucial role for Feltman in securing the funding for the ENIAC project. Feltman also served as a liaison between the Ballistics Division and Mauchly.

M65 atomic cannon Feltman also played an important role in the development of the M65 atomic cannon—nicknamed "Atomic Annie". Robert Schwartz began the design of a small tactical nuclear weapon at the Pentagon in 1949. Eventually, his project was transferred to the Picatinny Arsenal in Dover, New Jersey. Schwartz finished his design, and Feltman took on the important role of selling the project to the Pentagon. In July 1954, the Technical Division Laboratory at the Picatinny Arsenal was renamed the Samuel Feltman Laboratories.

Worked examples

Example 1 — a first encounter with Samuel Feltman

Start with the simplest possible case. Write down what Samuel Feltman 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 Samuel Feltman 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 Samuel Feltman 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 Samuel Feltman

In research
Samuel Feltman 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 Samuel Feltman 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
Samuel Feltman is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1899 births, 1951 deaths, 20th-century American people, so understanding it makes those chapters shorter.
In everyday life
Look for Samuel Feltman 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.
