Zachary (Zack) Landau of Bellevue, WA passed away suddenly on April 7. Born May 26, 1983 in New Haven, CT, he was the second child of Rick and Kathy Landau. He graduated from Hamden Hall High School in 2001. He graduated from Rochester Institute of Technology in 2006.

He leaves behind his wife Winifred, sons Hayden and Hunter, father Rick (Barbara), mother Kathy (Robert), brothers Ryan (Yi) and Cory (Whitney), his grandmother Leona, mother-in-law Anna, numerous cousins, some who were close as siblings, aunts, uncles, and step-siblings.

Zack developed an intense interest in computers at an early age. He self-taught DOS, Windows, numerous programming languages and became an expert on Linux. At the age of 14, he had a paper published in a Russian magazine. Zack was an early and devout contributor to free “open source” software. He voluntarily contributed to many open source projects, including Linux. Much of the code he created is still used today.

After college, he worked at ASML in Wilton before moving to Silicon Valley and taking a job with HP. There, he engineered software for some early tablets and mobile devices. He then moved on to Facebook, where he was a senior software developer for 9 years, working in Palo Alto, Vancouver, and Seattle.

He was adored by his two sons. His entire extended family loved him deeply and will miss him dearly.
