Key takeaways

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

Reference excerpt

Lorenzo's Oil is a 1992 drama film directed and co-written by George Miller. It is based on the true story of Augusto and Michaela Odone, parents who search for a cure for their son Lorenzo's adrenoleukodystrophy (ALD), leading to the development of Lorenzo's oil. The film was shot in Pittsburgh, Pennsylvania, primarily from September 1991 to February 1992. It had a limited release in North America on December 30, 1992, with a nationwide release on January 15, 1993. Though it was a box office disappointment, grossing $7.2 million against its $30 million budget, the film was generally well received by critics and garnered two nominations at the 65th Academy Awards.

Plot Lorenzo is a bright and vibrant young boy living in the Comoro Islands, as his father Augusto Odone works for the World Bank and is stationed there. However, after relocating with his parents to the United States, he begins to show signs of neurological problems, such as falling, loss of hearing, tantrums, etc. The boy is diagnosed as having adrenoleukodystrophy (ALD), which is fatal within two years. Failing to find a doctor capable of treating their son's rare disease, Augusto and his wife, Michaela, set out on a mission to find a treatment to save their son. In their quest, the Odones clash with doctors, scientists and a support group that is skeptical that anything could be done about ALD, much less by laypeople. But they persist, setting up camp in medical libraries, reviewing animal experiments, enlisting the aid of Professor Gus Nikolais, badgering researchers, questioning top doctors all over the world and even organizing an international symposium about the disease. Despite research dead-ends, the horror of watching their son's health decline and being surrounded by skeptics (including the coordinators of the support group they attend), they persist until they finally hit upon a possible therapy. The Odones sponsor an international meeting of scientists doing research on ALD, requiring two conditions ahead of time. First they insist that the meeting focus on potential treatments and second, they require that they be allowed to participate, despite being non-scientist laypeople. The pivotal scene in the movie portrays this meeting, in which the scientists are presenting their research. When Dr. William B. Rizzo mentions his studies in which the addition of oleic acid to cultured cells blocked accumulation of the factors which cause ALD, the Odones jump into the conversation, asking if this oil might help their son. Although the scientists play down their hope, pointing out that it would take years of work to produce the oil and test in clinical trials, the Odones seize the promise of this possible curative treatment. As the scene ends, Michaela Odone is shown beginning the effort to find someone able and willing to produce the same oil Dr. Rizzo gave to his cells. They obtain oleic acid from an industrial manufacturer of lubricants, but this only lowers Lorenzo's levels by 50% before leveling off, and they realize they are only countering some of the shorter chains produced by one enzyme. To remove the other, they will have to add a distillation of erucic acid. They contact over 100 firms around the world until they find an elderly British chemist, Don Suddaby, who is working for Croda International and is willing to take on the challenge of distilling the proper formula. The Odones obtain a precious vial of the oil (actually containing two specific long chain fatty acids, isolated from rapeseed oil and olive oil) and add it to their son's diet. This treatment proves successful in normalizing the accumulation of the very long chain fatty acids (which had been causing their son's steady decline), as measured in blood levels. This treatment halts the progression of his disease and is dubbed "Lorenzo's Oil". This oil is soon found to be successful in preventing the progression of harm in other patients with ALD. Meanwhile, Lorenzo has a great deal of neurological damage, and the Odones are dismayed to see that the oil can reverse their son's symptoms only very, very slowly. The Odones realize that more rapid improvement of their son's severe condition will require treatments to repair the myelin sheath (a lipid insulator) around the nerves, and Augusto is shown taking on the new challenge of organizing biomedical efforts to heal myelin damage in patients. Lorenzo, at the age of 14, shows definite improvement (swallowing for himself and answering "yes" or "no" questions by blinking) and it is revealed that he has regained his sight, can move his head from side to side, vocalize simple sounds and is learning to use a computer. The movie ends with scenes of ALD patients who were treated with Lorenzo's Oil earlier in the course of their disease. In these patients, the devastating neurological degeneration from which Lorenzo suffered was prevented.

Cast

Production Principal photography for Lorenzo's Oil began on September 9, 1991, in the Pittsburgh suburb of Ben Avon, Pennsylvania and continued throughout the city and area. Possibly to emphasize the "everyman" aspect of the plot (the notion that a cure could affect families and individuals anywhere), many smaller roles were played by inexperienced actors or non-actors with unusual physical features and mannerisms. For example, the poet James Merrill was noticed by a casting director at a New York public reading of his poetry. His rarefied speaking cadences were used in a symposium scene in which he played a questioning doctor.

Music The film uses Allegri's Miserere, Edward Elgar's cello concerto, as well as Barber's Adagio for Strings and Mozart's Ave verum corpus K.618. The opening song is "Kijana Mwana Mwali" (Swahili, "Song about a Young Lady"), sung by the Gonda Traditional Entertainers. A 1960 recording of Maria Callas with the La Scala orchestra and chorus is heard singing selections from Bellini's Norma at several points. The music for the Easter Midnight Mass scene is a Russian Orthodox Church hymn, "Bogoroditse Devo" (Rejoice, O Virgin) from "Three Choruses from 'Tsar Feodor Ioannovich'", taken from the album Sacred Songs of Russia by Gloriae Dei Cantores. Other music include Barber's Agnus Dei and Mahler's Symphony No. 5. The original music from the motion picture soundtrack was scored and composed by Stewart Copeland.

Worked examples

Example 1 — a first encounter with Lorenzo's Oil

Start with the simplest possible case. Write down what Lorenzo's Oil claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Lorenzo's Oil 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 Lorenzo's Oil 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 Lorenzo's Oil

In research
Lorenzo's Oil appears in biology 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 Lorenzo's Oil 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
Lorenzo's Oil is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1992 American films, 1992 English-language films, 1992 drama films, so understanding it makes those chapters shorter.
In everyday life
Look for Lorenzo's Oil 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.
