Ralph Samuelson

Ralph Samuelson is a science 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 Ralph Samuelson rather than just read about it. In short: Ralph Wilford Samuelson (July 3, 1903 – August 28, 1977) was the inventor of water skiing, which he first performed in the summer of 1922 in Lake City, Minnesota, just before his 19th birthday. Samuelson was already skilled at aquaplaning—standing on a board while being pulled by a powerboat—but he hoped to create something like snow skiing on the water.

Key takeaways

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

Reference excerpt

Ralph Wilford Samuelson (July 3, 1903 – August 28, 1977) was the inventor of water skiing, which he first performed in the summer of 1922 in Lake City, Minnesota, just before his 19th birthday. Samuelson was already skilled at aquaplaning—standing on a board while being pulled by a powerboat—but he hoped to create something like snow skiing on the water. Lake Pepin, a wide portion of the Mississippi River between Minnesota and Wisconsin, was the venue for his experiments.

Patent Samuelson did not patent his invention, nor was his work sufficiently publicized at the time to prevent U.S. Patent 1,559,390 for water skis from being subsequently issued, on October 27, 1925, to prolific inventor Fred Waller of Huntington, New York. Waller marketed his product as "Dolphin Akwa-Skees". Waller later invented the cinema widescreen motion picture system, and in 1952's This Is Cinerama, the first feature film released in the panoramic format, water skiing at Cypress Gardens, Florida, was a prominently featured subject. Famed journalist Lowell Thomas was an early investor in Cinerama, and in his introduction to the book Water Skiing (1958, Prentice-Hall), by Dick Pope, Sr., creator of Cypress Gardens, Thomas described the connection between Waller and water skiing's prominence as a subject in the motion picture. In several instances in the book, Pope reiterates—erroneously, we now know—that Waller was the first to invent water skis.

Early attempts Samuelson's early attempts included using staves from wooden barrels and snow skis before he created new skis made of pine boards 8 feet long and 9 inches wide (240 × 23 cm). He bent up the front tips after softening the wood by boiling them in his mother's copper kettle. Gaining confidence on the water, he began jumping wakes, but broke the original skis (the remains of which were believed to be found on a beach on Pepin) in one landing. His slightly modified second pair still exists; today they are at the Lake City Chamber of Commerce, in Lake City, Minnesota. Samuelson first succeeded on June 28, 1922, by starting off wearing skis while standing on top of an aquaplane board, and then slipping one foot and then the other into the water.

Ski jumping He attracted a lot of attention locally in the following days and weeks. On July 8, 1925, Samuelson went on to perform the first ski jump on water. He fell flat in his first attempt, but soon greased the launch platform with lard and succeeded on the second try. Also that year, on August 27, 1925, he became the first speed skier as he found himself racing across the water at 80 mph (130 km/h), pulled by a Curtiss flying boat that flew just above the waves.

Later years In his later years, Samuelson moved to Pine Island, Minnesota where he was a turkey farmer. He was a guest of honor at a water skiing 50th anniversary in 1972, and was inducted into the Water Ski Hall of Fame on January 22, 1977. When he returned to Minnesota, he began to suffer the effects of cancer, and died in Pine Island on August 28, 1977.

Worked examples

Example 1 — a first encounter with Ralph Samuelson

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

In research: Ralph Samuelson appears in science 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 Ralph Samuelson 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: Ralph Samuelson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1903 births, 1977 deaths, 20th-century American people, so understanding it makes those chapters shorter.
In everyday life: Look for Ralph Samuelson 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.
