LONDON (AP) -- Edward Haughey, who founded a world-leading veterinary drugs company and became Northern Ireland's wealthiest man, has died after his helicopter crashed in thick fog.
Leaders from across Britain and Ireland paid tribute Friday to the 70-year-old Haughey, who founded Norbrook Laboratories and built it into a worldwide exporter of drugs for livestock. His estimated worth of 650 million pounds ($1.1 billion) included several castles and country estates and an extensive art collection.
Police say he and three others died Thursday night when an AgustaWestland helicopter operated by Haughey's own helicopter charter business crashed after takeoff from one of his country mansions, Gillingham Hall in Norfolk, in eastern England.
Haughey, unusually, served both in Ireland's Senate and, since 2004, in Britain's House of Lords, where he was known as Baron Ballyedmond.
