Former OSI Board member Danese Cooper writes:
One of the pillars of the Indian FOSS Community passed away this week. Known for his humor, his uncompromising honesty and his generosity in sharing FOSS knowledge with like-minded individuals. His sudden passing after a massive heart attack has shocked and saddened his friends across the FOSS World.
Raj Mathur (aka OldMonk) was a founding member of the seminal Indian Linux Users Group, Delhi (aka ilug-d), and a very active member of the free and open source community. Well respected and extremely knowledgeable, he was often sought after for advice, which he readily dispersed. He was one of the earliest users and advocates of Linux and free software in India. Apart from contributions to the FOSS corpus with numerous packages released under the GNU GPL, he was also a regular member of the Free Software Award Committee, Director Emeritus of the Open Source Initiative and visiting professor at the Indian Statistical Institute, New Delhi1
Here is a 2008 interview with Raj shot at his home (site of many ilug-d meetings over the years) by Robin "Roblimo" Miller for Linux.com.
