John Knoll

Overview

John Knoll is a visual-effects supervisor at Industrial Light & Magic (ILM) who co-created Photoshop with his brother Thomas Knoll — and, decades later, originated the story for Rogue One: A Star Wars Story (Industrial Light & Magic; StarWars.com). He is not the brother who wrote Photoshop’s code: Thomas was the Michigan PhD student who did that, while John was the ILM effects man who asked for the tools, demoed them to companies, and wrote many of its image-processing plug-ins (University of Michigan Engineering; Computer History Museum). ILM describes him as an Academy-Award and BAFTA Award winner and one of its longest-serving visual-effects supervisors (Industrial Light & Magic).

The ILM man who needed a display tool

Knoll “got his start in miniatures and motion control at ILM in 1986” (Industrial Light & Magic). Michigan Engineering fills in the detail: he was a motion-control camera operator there, “convinced that computer graphics were the future of special effects,” but frustrated by the difficulty of displaying graphics on his new Macintosh (University of Michigan Engineering). He turned to his brother Thomas for help, asking him to write a few basic image-display tools, then asking for more and more advanced features, including tools to manipulate images (University of Michigan Engineering).

That persistence was the product’s sales engine. Thomas later said: “John has much more of an outgoing personality — he’s good at talking his way into projects. He was the one who was talking to companies, doing the demos and getting feedback” (University of Michigan Engineering). The Computer History Museum confirms the technical split: while Thomas worked on the base application, “John wrote many of the image-processing plug-ins” (Computer History Museum). In the summer of 1988 the brothers decided their program, then called Display, could be a credible commercial product, renamed it Photoshop, and sought a distributor (Computer History Museum). Adobe, encouraged by art director Russell Brown, bought a licence to distribute it (Computer History Museum).

A visual-effects career at ILM

Knoll stayed at ILM and built the career Photoshop had interrupted. ILM credits him as Head of Department Production-side Supervisor on “a myriad and diverse slate of projects, including the Star Wars prequels, the Pirates of the Caribbean franchise, Academy-award winning Animated Feature Rango, as well as A Star Wars Story: Rogue One, where he also served as Executive Producer” (Industrial Light & Magic). In his current roles as Executive Creative Director and Senior VFX Supervisor, he oversaw ILM’s work on seasons 1 and 2 of The Mandalorian, The Book of Boba Fett, and Disney’s Jungle Cruise (Industrial Light & Magic).

ILM also credits him with “pioneering and innovative computer graphics work throughout his lengthy tenure in the industry, including co-developing Photoshop with his brother Thomas and contributing to the recent workflow advancements in ILM’s virtual production toolset, StageCraft” (Industrial Light & Magic). The same page says his work has earned him “five additional visual effects Academy Award nominations as well as five additional BAFTA nominations” beyond his win (Industrial Light & Magic). One nomination slate is documented independently: at the 79th Academy Awards, the visual-effects nominees for Pirates of the Caribbean: Dead Man’s Chest were “John Knoll, Hal Hickel, Charles Gibson and Allen Hall” (fxguide).

Originating Rogue One

Knoll’s second act as a storyteller is documented by Lucasfilm itself: visual-effects supervisor John Knoll “also originated the story for Rogue One” (StarWars.com). “Knoll’s very first story treatment for Rogue One was titled Destroyer of Worlds,” StarWars.com reports, a phrase from Hindu scripture that J. Robert Oppenheimer used to describe his reaction to nuclear weapons development (StarWars.com). The film’s scientist, Galen Erso, was developed with Oppenheimer as a source of inspiration (StarWars.com).

The Photoshop story came full circle in 2019, when the Academy’s Scientific and Engineering Award went to Thomas Knoll and John Knoll “for the original architecture, design and development” of Photoshop, with Mark Hamburg honoured for continued development (Animation Magazine). The citation praised Photoshop’s “efficient, extensible architecture, innovative virtual-memory design and powerful layering system,” which led to its adoption as the preferred artistic tool for digital painting and image manipulation across the motion-picture industry (Animation Magazine).

What this profile does not claim

This profile does not pin Knoll’s Academy Award win to a single film: ILM calls him an Academy-Award winner and fxguide documents his Dead Man’s Chest nomination, but no Academy primary record was read in full in this pass, so the win is not attributed to a specific title here. It does not assert his birth date, which no tier1/tier2 source read in full verified. It does not present him as Photoshop’s sole creator or primary coder — that was Thomas — and it does not cover his full filmography, only the supervisory credits ILM itself lists.
