A BBC colleague called Walter last year an ‘industry legend’. For Terra Mater Factual Studios he is the heart and the head – incomparably experienced, highly dedicated and round-the-clock on duty.
For Walter a long dreamed adventure became true when after 30 years at Austria’s pubcaster ORF, he launched Terra Mater Factual Studios, a subsidiary company of Red Bull. Since January 1, 2011 TMFS is the new home of the former ORF UNIVERSUM team. As leader of the pack Walter heads the strategic development of the production house and together with his cherry-picked management team he steers the company in all creative, technological, financial and commercial matters.

Walter always felt a strong magnetic pull to approach the media industry. After completing his master degree in journalism at Vienna University he joined ORF as a freelance producer/writer/director and was lucky to be at the right time at the right place. As versioning producer he premiered a new slot called UNIVERSUM in 1987, as writer/director he worked on the first origination and the first major series of the soon very successful strand. In 1994 he took over the UNIVERSUM team and created the ORF Natural History Unit destined to become one of the leading brands in factual television worldwide.  When ORF made him Head of Specialist Factual in 2010, Walter soon knew that he and the whole ORF UNIVERSUM team had to move on to new and brighter horizons which led to the formation of TMFS.
As writer and executive producer Walter won numerous awards in his career, including an EMMY, several Pandas at Wildscreen and Teton awards at the Jackson Hole Wildlife Film Festival.
