Input: Consider Input: Question: How old was William Havemeyer's son when he retired from the sugar refining business? Passage:William Havemeyer (1770-1851) left Germany at age 15 and arrived in New York City after learning the trade of sugar refining in London. In New York he managed a sugar house on Pine Street before opening his own refinery on Vandam Street with his brother, Frederick Christian Havemeyer, who had come to New York in 1802. Together the two brothers operated the W. & F.C. Havemeyer Company sugar refineries, before passing the business on to their sons. His son William Frederick Havemeyer, retired from the sugar refining business in 1842 and entered politics, eventually serving three terms as Mayor of New York. In 1855 the family relocated their refineries to Brooklyn, where they remained as the business grew to acquire a commanding share of the United States sugar refining market under the leadership of Frederick's grandson, Henry Osborne Havemeyer. The Havemeyer refineries were incorporated as the American Sugar Refining Company in 1891 and became known as Domino Sugar in 1900. In the 20th century several of the family's members made notable contributions to the arts. Henry Osborne Havemeyer and his wife Louisine Havemeyer made large bequests to the Metropolitan Museum of Art and their daughter Electra Havemeyer Webb founded the Shelburne Museum.

Input: Consider Input: Question: Who was older the year that Lucic signed with the Bruins, Brad Winchester or Jonathan Bernier? Passage:In the 2007 off-season, Lucic signed an entry-level contract with the Bruins on August 2. He had been chosen as the Giants' next team captain, but made the Bruins' 200708 opening roster out of training camp. He played in his first career NHL game on October 5, 2007, a 41 loss to the Dallas Stars, in which he fought opposing forward Brad Winchester. His first goal came a week later on October 12 against Jonathan Bernier, a game winner, in an 86 win against the Los Angeles Kings. By also fighting Kings forward Raitis Ivanans and notching an assist, he recorded a Gordie Howe hat trick (an unofficial statistic constituting a goal, an assist and a fight in one game). Unsure of whether the Bruins would keep him or return him to junior, he stayed in a downtown hotel in Boston to start the season. However, Lucic made enough of an impression during his first set of games with the Bruins, showing grit and consistent willingness to fight (he recorded 13 fighting majors in his rookie season), that they decided to keep him in the lineup. Bruins management informed the Giants prior to Lucic's tenth game, accounting for the NHL's nine-game maximum for junior-eligible players to stay with their NHL club without initiating their contract. He was chosen to participate in the 2008 NHL YoungStars Game and finished his rookie campaign with eight goals and 27 points. Towards the end of the season, he was voted by Bruins fans for the team's Seventh Player Award for exceeding expectations. Matched up against the first-seeded Montreal Canadiens in the opening round, Lucic scored his first Stanley Cup playoff goal in Game 3 on April 13, 2008. He finished his first NHL post-season with two goals as the Bruins were eliminated by the Canadiens in seven games.
