Jon Louis Bentley (born February 20, 1953 in Long Beach, California) is a researcher in the field of computer science. He is credited with the invention of the k-d tree.

Bentley received a B.S. in mathematical sciences from Stanford University in 1974, and M.S. and Ph.D in 1976 from the University of North Carolina at Chapel Hill; while a student, he also held internships at the Xerox Palo Alto Research Center and Stanford Linear Accelerator Center. After receiving his Ph.D., he joined the faculty at Carnegie-Mellon University as an assistant professor of computer science and mathematics. At CMU, his students included Brian Reid, John Ousterhout, Jeff Eppinger, Joshua Bloch, and James Gosling, and he was one of Charles Leiserson's advisors. Later, Bentley moved to Bell Laboratories.

He found an optimal solution for the two dimensional case of Klee's measure problem: given a set of n rectangles, find the area of their union. He and Thomas Ottmann invented the Bentley–Ottmann algorithm, an efficient algorithm for finding all intersecting pairs among a collection of line segments. He wrote the Programming Pearls column for the Communications of the ACM magazine, and later collected the articles into two books of the same name. He has published or presented over 200 papers.

Jason Bradbury is a television presenter and children's author.

The third book, Cyber Gold was published on 7 April 2011.

Bradbury's roots lie in the stand-up comedy circuit where he started out in a double-act with David Walliams of Little Britain fame. Before they explored London’s stand-up clubs, Bradbury and Walliams formed their own comedy club with fellow performers Myfanwy Moore (producer of Little Britain) and Simon Pegg (Star Trek, Shaun of the Dead).

He is on the judging panels for the BAFTA Video Game Awards and the Media Guardian Innovation Awards.

Bradbury's first ever TV show was a cable show called Tellywest, where he worked alongside Sacha Baron Cohen (Ali G/Borat). He has also hosted shows on Trouble TV (T Spot, Trouble @ Breakfast, Jason On Your Doorstop, Trouble Radio), Bravo TV (FHM Top 100 Girls, World's Most Amazing Videos, Mercenaries), Sky 1 (The Hit Mix co-presented with Gail Porter), Channel 4 (Under The Moon), LWT (Live at The Capital Café alongside Dani Behr), and The Big Breakfast. He is the host of the prime time game show Don't Scare the Hare which made its debut on BBC One on 23 April 2011. The show was narrated by Sue Perkins but the programme was scheduled to run for 9 episodes (including a compilation show) but it was axed after 3 episodes due to poor ratings.
