Paul Le Roux

Paul Le Roux is a physics 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 Paul Le Roux rather than just read about it. In short: Paul Calder Le Roux (born 24 December 1972) is a former programmer, former criminal cartel boss, and informant to the US Drug Enforcement Administration (DEA). In 1999, he created E4M, a free and open-source disk encryption software program for Microsoft Windows, and is sometimes credited for open-source TrueCrypt, which is based on E4M's code, though he denies involvement with TrueCrypt.

Key takeaways

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

Reference excerpt

Paul Calder Le Roux (born 24 December 1972) is a former programmer, former criminal cartel boss, and informant to the US Drug Enforcement Administration (DEA). In 1999, he created E4M, a free and open-source disk encryption software program for Microsoft Windows, and is sometimes credited for open-source TrueCrypt, which is based on E4M's code, though he denies involvement with TrueCrypt. Le Roux was arrested on 26 September 2012 for conspiracy to import narcotics into the United States, and agreed to cooperate with authorities in exchange for a lesser sentence and immunity to any crimes he might admit to later. He subsequently admitted to arranging or participating in seven murders, carried out as part of an extensive illegal business empire. Le Roux was sentenced to 25 years in prison in June 2020.

Early life Le Roux was born on 24 December 1972, at Lady Rodwell Maternity Home in Bulawayo, in what was then the republic of Rhodesia (present-day Zimbabwe), and given up for adoption. His birth certificate gives his first name as "unknown" and makes no mention of his father. His biological mother's identity has not been disclosed; one source claims she was a poor teenager, while another states that his maternal grandmother was married to a US senator. Aged two months, he was adopted by a couple living in the asbestos-mining town of Mashava and given his future name, Paul Calder Le Roux. Although several family members became aware over the years, his parents never informed him of his adoption, and Le Roux only discovered the truth in 2002. Le Roux also had a younger sister. Following political events in 1980 that ended the Rhodesian Bush War and Robert Mugabe assuming power and ending white minority rule, Le Roux's family relocated to South Africa in 1984 for better schooling opportunities. They found a new home in the mining town of Krugersdorp, where Le Roux's father started a company managing coal-mining operations, soon bringing wealth to the family. Shortly after, Le Roux was given his first computer in exchange for washing his father's car. As a teenager, he was described as tall, trim and handsome, though not very social and not interested in sports. He was obsessed with the video game Wing Commander, which he played on his gaming console connected to the family TV. At around 15 or 16 years old, Le Roux was arrested for selling pornography following a police search of the family home. The family was able to keep the incident out of the public eye. Following his arrest, Le Roux became even more reclusive. An excellent student, he refused to learn Afrikaans—mandatory in South African schools — calling it a "dead language" and eventually dropping out of school at age 16. He enrolled in a local programming course, in which he excelled, completing the one-year course in eight weeks. Upon returning from a family holiday trip to the US, 18-year-old Le Roux decided to leave South Africa, and departed to the UK eight months later. He found work as a programmer, and, in 1994, met his future wife, Michelle. After six months in the US, he followed Michelle to Australia in 1995. The couple married and Le Roux acquired Australian citizenship. They lived in Perth and Sydney. Reports are contradictory regarding children of the marriage – some sources mention a son, while others claim Le Roux's first child (a son) was with his second wife. Le Roux has revealed little about his early life, and most of it was uncovered by journalist Evan Ratliff, relying mainly on an initially unnamed source close to Le Roux. He would later name Le Roux's cousin and former employee Mathew Smith as a source.

Worked examples

Example 1 — a first encounter with Paul Le Roux

Start with the simplest possible case. Write down what Paul Le Roux claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Paul Le Roux 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 Paul Le Roux 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 Paul Le Roux

In research
Paul Le Roux appears in physics 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 Paul Le Roux 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
Paul Le Roux is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1972 births, 21st-century American criminals, Arms traders, so understanding it makes those chapters shorter.
In everyday life
Look for Paul Le Roux 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.
