Reference excerpt

Iwan Serrurier (September 21, 1878 – 1953) was a Dutch-American electrical engineer notable for inventing the Moviola.

Career Iwan was born in Leiden, Netherlands to Lindor Serrurier, director of the city's ethnographic museum, and Martina Lindo. In June 1903, Serrurier married Catharina Damme in Utrecht. Soon after, they moved to the United States and settled in Pasadena, California, where their son Mark was born in May 1904. Serrurier sold real estate and worked for the Southern Pacific Railroad as a draftsman. In 1917 Serrurier designed a home movie projector, which he called the "Moviola", since he envisioned it being used in households similarly to the Victrola home phonograph. However, the Moviola's $600 price point (equivalent to $10,400 in 2023) meant few sold when it was first marketed in 1923. An editor at Douglas Fairbanks Studios suggested that Serrurier should adapt the device for use by film editors; he did this and the Moviola as an editing device was born in 1924. Serrurier expanded the Moviola Company over the following years, until his retirement in the 1940s. Iwan Serrurier died in 1953. In 1979, Mark Serrurier accepted an Academy Award for Technical Achievement on his and his father's behalf for their contribution to movie editing.

Worked examples

Example 1 — a first encounter with Iwan Serrurier

Start with the simplest possible case. Write down what Iwan Serrurier 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 Iwan Serrurier 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 Iwan Serrurier 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 Iwan Serrurier

In research: Iwan Serrurier 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 Iwan Serrurier 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: Iwan Serrurier is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1878 births, 1953 deaths, Academy Award for Technical Achievement winners, so understanding it makes those chapters shorter.
In everyday life: Look for Iwan Serrurier 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.
