Robert Sayre (born 1978) is a software developer who wrote the Atom syndication specification along with Mark Nottingham. Sayre joined Mozilla in 2006, where he worked until 31 May 2011 as an engineering director.[1] He previously worked for the digital marketing agency IconNicholson as a software engineer.

Sayre was a speaker at the IETF annual meeting in 2007, the Google Test Automation Conference in 2007 and XTech 2006 in Paris. He wrote "Atom: The Standard in Syndication," an article published in the July/August 2005 issue of the journal IEEE Internet Computing, and is a former developer of a Mac client for the Soulseek file-sharing service.

While working at Mozilla, Sayre discovered in 2010 that the Internet Explorer browser might have cheated on the popular SunSpider JavaScript benchmark. As he was benchmarking Firefox 4 against other browsers, he found that Internet Explorer 9 was 10 times faster than other browsers in one test in SunSpider. When he made two different trivial changes to the benchmark code for that particular test, "Internet Explorer 9 took around 20 times longer," reported the tech news site Digitizor.[2]

Personal life[edit]

Sayre lives in San Francisco and graduated from Syracuse University in 2000. At age 2, he was diagnosed with a Wilms' tumor.[3] He's a former resident of France and Tunisia.
