Dan Duncan, big game hunter, philanthropist

Houston billionaire and energy magnate Dan Duncan, who died Monday at 77, was also known as one of the modern world's most prolific big game hunters, taking 360 species on six continents and having 550 entries in the Safari Club International record book. Though usually low-key, Duncan made news in 2002 when it was reported he illegally killed moose and sheep from a helicopter in Siberia. A grand jury declined to indict Duncan, though charges were brought against his guide. The Houston Chronicle.
