Jan Jacobsen (1588/89 – 1622) was a Flemish naval commander and Dunkirker during the Eighty Years' War. He became a posthumous hero when, after battling an enemy fleet for over 13 hours, he destroyed his own ship rather than surrender.[1]

Key Information

Biography

[edit]

He was the son of Spanish admiral Michel Jacobsen and great-uncle of French admiral Jean Bart. On 3 October 1622 Jacobsen put out from Ostend on his first expedition as a captain of one of the king's frigates. His ship was part of a three-ship flotilla, with the intention of locating the Dutch Baltic convoy, accompanied by Spanish privateers Pedro de la Plesa and Juan Garcia. Jacobsen failed to elude the Dutch blockaders patrolling off the Flemish coast[2] and was soon in a running battle with nine Dutch warships which was to last for thirteen hours. He disabled two of them before finally fought to a standstill with his mast, rudder and sweeps shot away.

The Dutch called upon Jacobsen to surrender and offered quarter, but, rather than let one of the king's ships fall into the hands of the enemy he exploded his powder store. In doing so he crippled the two Dutch ships alongside and caused considerable loss of life on board them but at the cost of destroying himself, his ship and much of what remained of his crew.[3] Initial reports had Jacobsen putting the match to the powder himself, but at least one later account records that he had been shot through the thigh and gave the order to explode the powder store to one of his men.[4] Surviving members of his 170-man crew [5] that were picked up were hanged as pirates.

This incident was comparable to English admiral Sir Richard Grenville and the Revenge and created a mystique around the Dunkirkers, and the figure of Jacobsen in particular, at the very beginning of the second phase (1621–1648) of the Eighty Years' War.[6] The event was reported in contemporary newspapers, such as the Nieuwe Tijdinghen printed in Antwerp,[7] and was the subject of at least one contemporary ballad, Kapiteyn Jacobus, that likened Jacobsen to Samson.[8]

from Grokipedia
Jan Jacobsen was a Norwegian engineer, inventor, and film technology pioneer known for his innovative contributions to motion picture cameras, anamorphic lenses, large-format film systems, and front-projection visual effects. Born in Mandal, Norway, in December 1916, he developed an early interest in cinematography, constructing his first 9.5 mm camera at age 16 before studying radio and communication engineering in Hannover, Germany, where he built a 16 mm single-system camera with optical sound. After returning to Oslo, Jacobsen established a mixing studio with magnetic sound recording capabilities and created custom optical sound cameras, laying the foundation for his later work in film sound and equipment design. Following World War II, he spent time in the United States building compact 16 mm cameras and later designed anamorphic lenses in London, including ScaniaScope and HammerScope systems, before joining Arnold & Richter (ARRI) in Munich to develop the UltraScope series, pioneering anamorphic elements placed behind the main lens to enable wide-angle capabilities and the first anamorphic zoom lens. In the 1960s, he founded Modern Cinema Systems (MCS) and developed the MCS-70, a European 65 mm large-format process used on productions such as Flying Clipper (1962), Old Shatterhand (1964), and others, while also creating a prototype mechanism that became the basis for the IMAX 15-perf horizontal camera movement. His later innovations included the DualScreen front-projection system, for which he received an Academy Award, and visual effects contributions to international films including Das Boot (1981), Superman (1978), and Fedora (1978). Jacobsen died on 23 June 1998 in Augsburg, Germany.

Early life and education

Birth and early interest in filmmaking

Jan Jacobsen was born in December 1916 in Mandal, Norway. As a teenager, he became fascinated with movies and the emerging medium of cinema. At the age of 16, Jacobsen assembled his first 9.5 mm camera using simple tools and parts he could gather, demonstrating an early hands-on interest in film technology that would define his later career.

Education and first inventions

Jan Jacobsen studied radio and communication engineering at a technical college in Hannover, Germany. During his college years, he built a 16 mm single-system camera with optical sound in his own workshop, showcasing his early ingenuity in combining image capture with synchronized audio recording. He also met Dr. Curt Stille, who was actively developing improvements in magnetic sound recording, an encounter that influenced Jacobsen's later efforts to advance magnetic sound technologies. After completing his studies, Jacobsen returned to Oslo to begin his professional work in the film industry.

Early career in Norway

Post-war sound recording work

After the conclusion of World War II, Jan Jacobsen remained active in Oslo's film industry, applying his expertise in sound technology to Norwegian productions. He had previously built a mixing studio equipped with magnetic sound in Oslo and constructed a custom "J.J." optical sound camera that enabled dubbing sound on sound, with this installation remaining in operation until the 1960s. In the immediate post-war years, Jacobsen provided sound contributions to several Norwegian films, serving in roles such as sound recordist or sound technician. His credits during this period include sound on Englandsfarere (1946), Så møtes vi i morgen (1946), Vi seiler (1948), Kampen om tungtvannet (1948), sound recordist on Vi vil skilles (1952, credited as Jan W. Jacobsen), and sound on King of Skating (1953). These post-war roles built on his earlier sound work, which included credits on films such as Brudekronen (1944). Overall, Jacobsen accumulated approximately twelve sound department credits on Norwegian films between 1942 and 1953. His post-war sound recording efforts reflected the technical foundation he had developed earlier, including self-built sound devices during his education.

Independent camera and sound system development

Shortly after World War II, during a brief visit to the United States, Jacobsen built the extremely compact EMP 16 mm camera (Envelope Minimum Possible), housed within the shell of a bombsight apparatus from an old Lockheed bomber. He arranged to rent machine time at night in Kenneth Richter's shop near New York for one dollar per hour, and despite widespread skepticism that the device would function, it performed successfully and was later used for filming commercials. Back in Oslo during the 1950s, Jacobsen modified a Bell & Howell studio camera by adding a 17.5 mm drive to support magnetic sound recording, while also constructing an associated amplifier, in order to produce a 35 mm camera system for Swedish film productions. Though the overall setup was bulky, it proved reliable and remained in use for many years. In 1954, Jacobsen relocated to London to develop anamorphic lenses.

International technical innovations

Anamorphic lenses and collaborations

In 1954, following the introduction of CinemaScope, Jan Jacobsen was invited to London, then regarded as the center of the European film industry. There he developed his own anamorphic lenses, which were later marketed under names including ScaniaScope and HammerScope, among others. The quality of these lenses led to an invitation from Arnold & Richter (ARRI) in Munich, Germany, to join the company. At ARRI, Jacobsen developed the UltraScope series of anamorphic lenses. A significant innovation in his approach was placing the anamorphic element behind the basic lens rather than in front of it, the standard practice at the time. This placement substantially reduced distortion, especially in wider lenses where front-mounted elements had previously caused greater problems. He extended this principle to create what is described as the first anamorphic zoom lens, by positioning the anamorphic element behind an existing zoom lens, an idea noted for its simplicity despite having eluded earlier designers.

Large-format camera systems and MCS-70

In 1959, Jan Jacobsen began developing the VarioScope, a 65/70 mm large-format system designed to allow variable aspect ratios on screen, with wide framing for landscapes and taller framing for close-ups, controlled via a control track that also managed stereo sound. The prototype was tested in England and the United States but remained unfinished due to the complexity of its projection requirements. A demonstration of the VarioScope camera attracted interest from German cinema owner Rudolf Engelbrecht and producers Rudolf Travnicek and Aldo von Pinelli, leading to the founding of Modern Cinema System (MCS) in Munich as a European counterpart to American 65/70 mm processes like Todd-AO. Under Jacobsen's technical leadership, the company built six compact MCS Superpanorama 70 field cameras using 65 mm film with five perforations per frame, featuring high-precision claw movement, rotating mirror reflex viewfinders, and compatibility with medium-format still lenses including a special 17 mm wide-angle lens designed by Jacobsen. The first production to employ the MCS-70 system was Flying Clipper (1962), where the cameras performed reliably for both ground and aerial photography, although one field camera was lost overboard and remains in the Mediterranean Sea; the unfinished VarioScope camera was also used during this production. Subsequent MCS-70 films included Old Shatterhand (1963/64) and Der Kongress amüsiert sich (1966), while for Uncle Tom's Cabin (1965) Jacobsen constructed two additional blimped studio cameras to provide near-silent operation on set. In 1963, Jacobsen built a specially quiet and compact 65 mm five-perforation camera for MGM Studios in Copenhagen, noted for its elegant design and use of a friend's machine shop. In the mid-1960s, two re-acquired MCS cameras were rebuilt to record side-by-side CinemaScope 3D images on 65 mm film, with a matching projection lens for single-strip presentation; this HiFi-Stereo-70 process was used on Operation Taifun (starring Alain Delon). Between 1967 and 1969, Jacobsen designed and constructed a prototype camera movement for the Toronto IMAX group in the 15-perforation 65 mm horizontal format, employing a double set of pull-cross claws to advance 15 perforations per cycle; he filed a patent for this mechanism on December 29, 1969, and recommended the Australian Rolling Loop projector design to the IMAX team for their system. MCS ceased feature-film production after the deaths of Travnicek in 1965 and Pinelli in 1967, with the company's cameras subsequently sold and their current locations largely unknown.

Front projection and visual effects contributions

Development of DualScreen system

Jan Jacobsen developed the DualScreen, a two-level front projection system intended for motion picture special effects photography. He constructed several portable versions of the DualScreen in his basement workshop in Augsburg, Germany, and sold these units to film studios in Vienna and Munich. For his work on this system, Jacobsen received a Technical Achievement Award from the Academy of Motion Picture Arts and Sciences at the 60th Academy Awards in 1988. The award citation reads: "To Jan Jacobsen for the application of a dual screen, front projection system to motion picture special effects photography." In his later years, Jacobsen experimented with an improved and faster pull-cross system for a VistaVision version of the DualScreen and built an additional 8-perforation camera to support these experiments.

Work on major feature films

Jan Jacobsen contributed front projection and process photography expertise to several major international feature films during the late 1970s and early 1980s, frequently in uncredited technical roles. His work often involved specialized equipment that supported visual effects compositing in high-profile productions. He collaborated with Wally Veevers on Superman (1978), developing a lightweight, mobile front projection unit that could be mounted on an ordinary dolly or crane for flexible on-set process work. Jacobsen also built a special VistaVision setup for the film. His contributions to Superman went uncredited. Jacobsen provided front projection for Fedora (1978, uncredited), process photography on The Humanoid (1979, credited as Jan W. Jacobsen), and uncredited front projection for Avalanche Express (1979) and Night Crossing (1982). He handled front projection for Das Boot (1981) and later for three episodes of its 1985 television mini-series adaptation. These projects drew on Jacobsen's DualScreen dual-screen front projection system, which earned him a Technical Achievement Award from the Academy of Motion Picture Arts and Sciences for its application to motion picture special effects photography.

Later years and legacy

Private workshop and final projects

After relocating to Germany, Jan Jacobsen settled in a house outside Augsburg, where he led a quiet and modest life while maintaining a small private machine shop in his basement. In this workshop, he continued inventing and building equipment throughout his later years. He constructed several portable DualScreen front projection set-ups there, which he sold to movie studios in Vienna and Munich. Jacobsen attempted to develop two new rolling-loop movement cameras—one in 16 mm and one in 35 mm—but these efforts did not succeed, leading him to abandon the concept. He later disassembled the 35 mm rolling-loop camera and rebuilt it. He also worked on refinements to his earlier innovations, including an improved and faster pull-cross system for the VistaVision version of his DualScreen system. Jacobsen built another 8-perforation camera for his experiments. In his final years, he applied for a patent on his "Flipping Focus" system and devoted much of his time to constructing cameras and lenses while pursuing new ideas and inventions in his machine shop.

Death and recognition

Jan Jacobsen died on June 23, 1998, at the age of 81 following cancer surgery in a hospital in Augsburg, Germany. He was renowned as an Oscar-winning movie pioneer and camera engineer whose prolific independent designs advanced cameras, anamorphic optics, large-format systems, and front projection techniques. Jacobsen's key contributions included the UltraScope anamorphic lenses, the MCS-70 Superpanorama camera series, an early IMAX camera, and the Dual Screen front projection system, for which he received a Special Photographic Technical Achievement Academy Award in 1987. He continued inventing until the end of his life, even applying for a patent on his "Flipping Focus" system while working in his small machine shop near Augsburg. His work earned him lasting recognition in the film industry as a brilliant engineer whose innovations influenced major motion picture technologies.
