Task: Question Generation
Input (English): Passage: The museum's founder Sigurður Hjartarson worked as a teacher and principal for 37 years, teaching history and Spanish at Reykjavík's Hamrahlid College for the last 26 years before his retirement. As a child, he owned a bull's pizzle, which was given to him to use as a cattle whip. He began collecting penises after a friend heard the story of the bull's penis in 1974 and gave him four new ones, three of which Sigurður gave to friends. Acquaintances at whaling stations began bringing him whale penises as well, and the collection grew from there, expanding through donations and acquisitions from various sources around Iceland.The organs of farm animals came from slaughterhouses, while fishermen supplied those of pinnipeds and the smaller whales. The penises of larger whales came from commercial whaling stations, although this source dried up after the International Whaling Commission implemented a global ban on commercial whaling in 1986. Sigurður was able to continue to collect whale penises by harvesting them from the 12–16 whales that fall victim to stranding on the Icelandic coast each year. He also obtained the penis of a polar bear shot by fishermen who found the animal drifting on drift ice off the Westfjords.Sigurður was assisted by his family, though not without some occasional embarrassment. His daughter Þorgerður recalls that she was once sent to a slaughterhouse to collect a specimen but arrived just as the workers were taking a lunch break: "Someone asked, 'What's in the basket?' I had to say, 'I'm collecting a frozen goat penis.' After that I said, 'I will never collect for you again.'" According to Sigurður, "Collecting penises is like collecting anything. You can never stop, you can never catch up, you can always get a new one, a better one."
The collection was at first housed in Sigurður's office at the college until he retired from his teaching job. He decided, more as a hobby than a job, to put it on public display in Reykjavík and was awarded a grant from the city council of ISK 200,000 to support the opening of a museum in August 1997. By 2003, it was attracting 5,200 visitors a year, of which 4,200 were from abroad. He put the museum up for sale in 2003, but also offered it to the city of Reykjavík as a gift. However, he was unsuccessful in obtaining financial support from the state or city. When he retired in 2004, he could no longer afford the rent on the museum's premises.
Output (English): What is the last name of the person to whom acquaintances at whaling stations began bringing whale penises?
