Activist investor Daniel Loeb's hedge fund Third Point is looking to replace Campbell Soup's entire board, The Wall Street Journal reported Thursday, citing people familiar with the matter. Such a campaign would shine an unprecedented spotlight on the three descendants of Campbell's founder who sit on the soup company's board. Two of those descendants, Bennett Dorrance and Mary Alice Dorrance Malone, together hold a 33 percent stake in Campbell. The fiercely private siblings, whose father served as Campbell chairman, have resisted past pressure to sell the company.
