David Sarif

David Sarif is the 57 year-old founder of Sarif Industries and Adam Jensen's employer in Deus Ex: Human Revolution.

Background
David Sarif is the founder and CEO of Sarif Industries, a moderately-sized biotechnology company based in North America. He is a well-preserved male in his late 50s, of average height and build, in decent shape. His features are Mediterranean. Judging by the screens in his office he is a fan of the Detroit Tigers.

The son of an immigrant family from Boston, Sarif was brought up to understand the value of hard work and dedication, and from an early age his insight into machines set the tone for the man he would become. He worked his way through university and from there to a scholarship at MIT, getting a Master's and an MBA before entering the prosthetics field.

Sarif believes in justice, progress, science and technology, civilization, human endeavor, and people. He is direct when dealing with others and unafraid to show emotions. Some find him blunt or pushy, others refreshing, even invigorating. His sense of honesty applies only to his behavior - he has no aversion to keeping secrets when appropriate; usually his demeanor lets him get away with it. In 2007, David Sarif promised to revitalize his home city of Detroit by introducing a new industry of mechanical augmentation to the city. Refitting disused automobile plants for the production of mechanical augmentations for military and civilian use, Sarif has nearly single-handedly revitalized the economy of the city and prevented its collapse. He is close friends with Hugh Darrow, the father of mechanical augmentation.

He was preparing for the augmentation debate in Washington, when the black-ops team, the Tyrants attacked the Sarif HQ in Detroit, killing several scientists, including his niece Megan Reed, and nearly killing the chief of security, Adam Jensen. Sarif opted to save Jensen and arranged for him to be mechanically augmented. While only Adam's left arm and chest cavity needed to be augmented in order to save his life, Sarif decided, as Jensen's medical proxy (employment contract clause), to replace most of Adam's body with cybernetic prosthetics.

Six months later, he pulled Jensen out of the sick leave when an extremist anti-augmentation group Purity First attacked the Milwaukee manufacturing plant, just as the production of top-secret military augmentation, the Typhoon Explosive System was to begin there. He sent Jensen to secure the data and rescue the hostages.

Upon Adam's return, Sarif had him retrieve the Neural Hub of the augmented Purity First hacker from the Detroit Police Department morgue, disable the transmitter in Derelict Row district that kept a backdoor open to SI network, and investigate abandoned bot factory complex in Highland Park.

Trivia
- You can find Sarif's portrait in his office that pictures him with both hands augmented. In the game, however, Sarif is shown with only his right hand augmented visibly. Whether it was intentional or not, remains unknown.
