Lanny Smoot

Lanny Smoot 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 Lanny Smoot rather than just read about it. In short: Lanny Smoot (born December 13, 1955) is an American electrical engineer, inventor, scientist, and theatrical technology creator. With over 100 patents, he is Disney's most prolific inventor and one of the most prolific Black inventors in American history.

Key takeaways

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

Reference excerpt

Lanny Smoot (born December 13, 1955) is an American electrical engineer, inventor, scientist, and theatrical technology creator. With over 100 patents, he is Disney's most prolific inventor and one of the most prolific Black inventors in American history. Throughout his career he has worked to inspire young people, especially Black youth, towards STEM.

Biography Lanny was born in Brooklyn, NY, USA, and later attended Brooklyn Technical High School. He attended Columbia University, supported by a Bell Labs Engineering Scholarship and received his Bachelor's degree in Electrical Engineering. He then started work at Bell Communications Research (Bellcore), and while working at Bell (later Telcordia), he also completed his Master's Degree in Electrical Engineering from Columbia. Smoot worked at Bell for two decades, where his mentors included James West, co-inventor of the electret microphone. Around 2000, he moved to Disney where he is currently a Disney Research Fellow.

Notable work At Bell, Smoot was known for his work on early development of video-on-demand and other video and fibre-optic technology. He anticipated a future where anyone could broadcast video. At Disney, Smoot's accomplishments include the drive system for the Star Wars BB-8 droid, interactive zoetropes for facial animation of objects, eye imaging for superhero masks and helmets, “Where’s the Fire?” at Innoventions (Epcot), many Haunted Mansion special effects, virtual interactive koi ponds in Hong Kong Disneyland, Fortress Explorations at Tokyo DisneySea, Power City" in Spaceship Earth (Epcot), and lightsabers for the Star Wars: Galactic Starcruiser experience. Other patented inventions include new ride technology and glassless 3D displays.

Worked examples

Example 1 — a first encounter with Lanny Smoot

Start with the simplest possible case. Write down what Lanny Smoot 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 Lanny Smoot 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 Lanny Smoot 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 Lanny Smoot

In research: Lanny Smoot 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 Lanny Smoot 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: Lanny Smoot is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, 20th-century African-American scientists, 20th-century American engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Lanny Smoot 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.
