Suspensor
the antigravity device of the Holtzman field
Suspensors were hovering devices that used the secondary phase of a Holtzman field generator to nullify gravity within limits set by mass and energy use. They buoyed everything from glowglobes and furniture to the bulk of Baron Vladimir Harkonnen.
The Holtzman suspensor was a hovering device that used the secondary low drain phase of a Holtzman field generator to nullify gravity within limits prescribed by relative mass and energy consumption. It was one of the most pervasive technologies of the Imperium, employed wherever weight had to be removed or controlled. (Dune)
Principle and origin#
The suspensor exploited the secondary, low drain phase of a Holtzman field generator to nullify gravity within certain limits set by the relative mass to be lifted and the energy available to consume. The original concept came from Norma Cenva while she worked for Tio Holtzman on the world of Poritrin. She based the device on Holtzman's original shield design, then heavily modified it herself. The first invention to employ the principle was the glowglobe, a hovering light source that came to illuminate the halls and chambers of the Imperium. (Dune; Dune: The Butlerian Jihad)
Uses#
Suspensors were used in chairs, tables, and structures that were too massive to be physically sound, among many other applications. Their most notorious use belonged to Baron Vladimir Harkonnen, whose grotesque obesity left him unable to support his own weight. The Baron relied on suspensor belts and harnesses to buoy his flesh and allow him to move and walk. (Dune)

Holtzman effect
The Holtzman effect was a scientific theory concerning the repellent force of subatomic particles. From it sprang the defensive shield, the suspensor, the glowglobe, and above all the folding of space that made instantaneous travel across the universe possible.

Baron Vladimir Harkonnen: the architect of the Atreides fall
Siridar-Baron Vladimir Harkonnen was the penultimate ruler of House Harkonnen and the chief architect of the downfall of Duke Leto Atreides. A gluttonous and cruel schemer, he conspired to seize Arrakis and the Golden Lion Throne before his House was destroyed in the war for Arrakis.

Norma Cenva
Norma Cenva was a mathematical genius of the Butlerian Jihad who designed the first foldspace ship, became the first Guild Navigator, and co-founded the Spacing Guild. She ultimately evolved into the disembodied Oracle of Time.

Poritrin
Poritrin was the third planet of Epsilon Alangue, held by many Zensunni Wanderers to be their planet of origin, and in the expanded universe a slave world where Zensunni captives laboured for the League of Nobles.
Tio Holtzman
Tio Holtzman was the celebrated savant of Poritrin credited with the Holtzman Effect and its shield technology, who took credit for the genius of Norma Cenva and died in a lasgun-shield explosion during a slave rebellion.

Dune Timeline: from the thinking machines to the end of Kralizec
A dated chronology of the Dune universe, from the first age of space travel and the Butlerian Jihad to Paul Atreides, the God Emperor, the Scattering and the last war with the machines. Events run oldest first, era by era, and every entry says which book it comes from.
Garun: Naib of the Museum Fremen
Garun was the Naib of Tuono, a village of Museum Fremen on Arrakis in the final years of the God Emperor Leto Atreides II. He played host to Duncan Idaho and Siona Atreides during their exile, was exposed by Idaho as a Fremen in costume only, and wanted nothing more than to become a true Fremen.

Shield
The shield was a protective energy field generated by Holtzman technology that surrounded its wearer and admitted only objects moving below a set velocity. Its ubiquity drove the Imperium back to blade combat, while its reaction to lasgun fire made directed energy weapons too dangerous to use.
