Mario Maccaferri

Mario Maccaferri 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 Mario Maccaferri rather than just read about it. In short: Mario Maccaferri (1900–1993) was an Italian luthier, classical guitarist, businessman, and inventor. He is noted for designing the guitar favored by jazz musician Django Reinhardt, and for designing plastic clothespins, plastic bath and kitchen tiles and the plastic Islander ukulele which sold millions of copies in the mid-1900s.

Key takeaways

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

Reference excerpt

Mario Maccaferri (1900–1993) was an Italian luthier, classical guitarist, businessman, and inventor. He is noted for designing the guitar favored by jazz musician Django Reinhardt, and for designing plastic clothespins, plastic bath and kitchen tiles and the plastic Islander ukulele which sold millions of copies in the mid-1900s. From 1939 he lived and worked in the United States. As of 2016 his daughter Elaine still runs the family company French American Reeds Inc.

Early life Maccaferri was born in Cento, Emilia-Romagna. At the age of 11 he was apprenticed to luthier Luigi Mozzani and took up the classical guitar. By 1923 he had established a reputation as a player and maker of classical guitars.

Musical career In 1933, Maccaferri injured his right hand in a swimming pool accident, ending his career as a concert performer, though he continued to work as a luthier and inventor.

Lutherie designs Maccaferri is best-known for designing the Selmer Maccaferri guitar played by Gypsy jazz legend Django Reinhardt. His design featured the distinctive “D-shaped” sound hole. Maccferri's innovations extended to materials as well: he was an early adopter of laminate backs and sides for guitars, and for instruments made entirely of plastic.

Plastic instruments

In 1941, Maccaferri patented a plastic woodwind reed, in 1947 he patented two plastic clothespin designs, and in 1949 he launched his line of plastic "Islander" ukuleles in collaboration with television star Arthur Godfrey, which would sell into the millions of units. Maccaferri also developed the Chord Master, an automatic chording device originally designed for the ukulele. In the 1950s, Maccaferri produced a line of plastic guitars, but they had little commercial success. Later in his career and up until his death, Maccaferri worked on the design for a plastic violin, which in 1990 was used at a performance at Carnegie Hall.

Worked examples

Example 1 — a first encounter with Mario Maccaferri

Start with the simplest possible case. Write down what Mario Maccaferri 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 Mario Maccaferri 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 Mario Maccaferri 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 Mario Maccaferri

In research
Mario Maccaferri 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 Mario Maccaferri 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
Mario Maccaferri is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1993 deaths, History of jazz, so understanding it makes those chapters shorter.
In everyday life
Look for Mario Maccaferri 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.
