Arri

Arri 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 Arri rather than just read about it. In short: Arri Group () (stylized as "ARRI") is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917.

Key takeaways

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

Reference excerpt

Arri Group () (stylized as "ARRI") is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917. It produces professional motion picture cameras, lenses, lighting and post-production equipment. It is cited by Hermann Simon as an example of a "hidden champion". The Arri Alexa camera system was used to shoot several films that won the Academy Award for Best Cinematography, including Hugo (2011), Life of Pi (2012), Gravity (2013), Birdman (2014), The Revenant (2015) and 1917 (2019).

History

Early history Arri was founded in Munich, Germany on 12 September 1917 by August Arnold and Robert Richter as Arnold & Richter Cine Technik. The acronym Arri was derived from the initial two letters of the founders' surnames, Arnold and Richter. In 1924, Arnold and Richter developed their first film camera, the small and portable Kinarri 35. In 1937, Arri introduced the world's first reflex mirror shutter in the Arriflex 35 camera, an invention of longtime engineer Erich Kästner. This technology employs a rotating mirror that allows a continuous motor to operate the camera while providing parallax-free reflex viewing to the operator, and the ability to focus the image by eye through the viewfinder, much like an SLR camera for photography. The reflex design was subsequently used in almost every professional motion picture film camera and is still used in the Arri Alexa Studio digital camera. The first Hollywood film to employ an Arriflex was the 1947 Humphrey Bogart and Lauren Bacall film Dark Passage in 1947. Over the years, more than 17,000 Arriflex 35s were built. The design was recognized with two Scientific and Technical Academy Awards in 1966 and 1982.

Rise and Appeasement under Nazi Rule (1926–1938) In its early years, ARRI grew steadily: by 1927, the company had 20 employees, and five years later, it had already doubled that number. When August Arnold and Robert Richter were not using their technology to produce films or segments for the newsreel (Wochenschau), they rented out their equipment to other film producers for a fee. This idea of renting equipment would later lead to the founding of ARRI Rental, now a major branch of ARRI's global business. In 1928, the company developed the KINARRI 16, the first 16mm camera—a hand-cranked amateur model soon replaced by an improved version with a spring mechanism. In 1934, ARRI released a mobile sound camera, but due to patent issues, it was only used for the production of two films. From 1927 onward, the company filmed the Reichsparteitage of the NSDAP, and after the party took power in Germany, ARRI ingratiated itself by sending letters presenting the firm as a longtime supporter. Richter and Arnold both joined the NSDAP in 1933. They hoped to gain protection, commissions, and recommendations for the renewed production of feature films under party-affiliated organizations. The company hired directors and screenwriters who were aligned with the cultural policies of Nazi Germany, but after only three feature films produced in 1934–35 it abandoned feature-film production. These films were Grenzfeuer (1934), written and directed by Hanns Beck-Gaden; Die Frauen vom Tannhof (1934), directed by Franz Seitz Sr. from a screenplay by Joseph Dalmann; and Es waren zwei Junggesellen (1935), directed by Seitz, with a screenplay by Dalmann and Joe Stöckel. In 1938, ARRI was commissioned to shoot a film documenting the destruction of the Old Main Synagogue in Munich. In 1937, ARRI presented the ARRIFLEX 35 at the Leipzig Spring Fair, the first mass-produced reflex film camera. Engineer Erich Kästner played a decisive role, bringing the rotating mirror shutter to production readiness in motion picture cameras. For the first time, the ARRIFLEX 35 allowed users to view the precise frame and focus distribution through the viewfinder without parallax error. The basic design of this camera is still used today in ARRI's digital ALEXA line.

Second World War (1939–1945) From 1939 onwards, the German military became a major customer for ARRIFLEX cameras, which were used for propaganda purposes. Sales to the film industry were largely restricted. Although ARRI was not classified as an armaments manufacturer, in 1942 production was relocated from Türkenstraße in Munich to Brannenburg, approximately 70 km away. On 13 July 1944, ARRI's Munich headquarters was completely destroyed in an Allied bombing raid. During the war, a copy of the ARRIFLEX—called the Cineflex—was developed in the United States, primarily for military applications. After 1945, when ARRI was again able to deliver precision-engineered ARRIFLEX cameras from U.S.-occupied Bavaria, the American copy disappeared from the market. Following the end of the war, ARRI immediately began rebuilding its headquarters in Munich. The reconstruction took place in several phases and lasted approximately ten years.

1950–1989

In 1952, Arri introduced the Arriflex 16ST, the first professional 16mm camera with a reflex viewing system. In 1965, a self-blimped 16mm camera was released: the Arriflex 16BL. The Arriflex 35BL followed in 1972 as a lightweight, quiet alternative to the rather heavy and cumbersome blimped cameras of the time. Also in 1972, Arri pioneered the development of daylight luminaires with the Arrisonne 2000 W. The Arriflex 16SR, launched in 1975, featured a redesigned viewfinder with a through-the-lens light meter. The Arriflex 765, a 65mm camera, was released in 1989, partly in response to the growing industry demand for 70mm release prints.

Worked examples

Example 1 — a first encounter with Arri

Start with the simplest possible case. Write down what Arri 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 Arri 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 Arri 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 Arri

In research
Arri 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 Arri 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
Arri is common in secondary-school and first-year university syllabi. It links to neighbouring topics Film and video technology, German brands, German companies established in 1917, so understanding it makes those chapters shorter.
In everyday life
Look for Arri 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.
