> Dear colleagues,
>
> It is my sad duty to inform you that Dr. TomClarkpassed away on 
> Tuesday, September 28 at the age of 82. The VLBI world has lost one of 
> its pioneers.
>
> Tom received a Ph.D. in astro-geophysics from the University of Colorado
> in Boulder. His dissertation involved building a very large 10 MHz 
> Radio Telescope on a mesa north of Boulder. After spending two years 
> as Werner von Braun’s Solar Physicist at NASA Marshall Space Flight 
> Center in Alabama, he moved to NASA Goddard Space Flight Center in 
> 1968. In 1969, he also joined the University of Maryland Physics & 
> Astronomy faculty.
>
> His various talents and connections were instrumental in establishing 
> the Goddard VLBI Group. He was the long-term principal investigator 
> for the VLBI activities at NASA GSFC and directed the program for over 
> 30 years until his retirement in 2001. In 2005, he became the first 
> non-Russian scientist to be awarded the Gold Medal of the Institute of 
> Applied Astronomy of the Russian Academy of Sciences for his lifetime 
> contributions to the development of VLBI.
>
> Tom was an avid amateur radio (ham radio) hobbyist. He was also very 
> fond of photography, traveling, and his supercharged Mini Cooper. 
> Please join me in sharing our condolences with Tom's family, friends, 
> and colleagues.

> With sadness,
