Some context: Todd Bertuzzi (born February 2, 1975) is a Canadian retired professional ice hockey winger of the National Hockey League (NHL). Known as a power forward, he has played in the NHL for the New York Islanders, Vancouver Canucks, Florida Panthers, Anaheim Ducks, Calgary Flames and Detroit Red Wings. Selected 23rd overall by the New York Islanders in the 1993 NHL Entry Draft, he played at the junior level with the Guelph Storm of the Ontario Hockey League (OHL) for four seasons.
Two years after his draft, Bertuzzi and the Islanders had not yet been agreed to a contract. With Bertuzzi eligible to re-enter the draft if the Islanders did not sign him by July 7, 1995, general manager Don Maloney made it apparent that he would use the team's second overall pick in the 1995 NHL Entry Draft to select him again if a contract could not be agreed upon by the required date. Moments before the midnight deadline, the Islanders were able to sign Bertuzzi to a four-year, US$4.6 million contract. His agent, Pat Morris, had reportedly wanted a similar deal to that of fellow Islanders prospect Brett Lindros - a five-year, $6.7 million contract signed the previous summer.  During training camp in September 1995, Islanders head coach Mike Milbury heralded Bertuzzi as the team's best performing forward. Making his NHL debut on October 7, 1995, he scored a wrap around goal against goaltender Blaine Lacher in a 4-4 tie with the Boston Bruins. Beginning the season on the team's top line with Zigmund Palffy and Travis Green, Bertuzzi finished his rookie year with 18 goals and 39 points over 76 games. The following season, Bertuzzi recorded 23 points in 64 games. The Islanders did not qualify for the playoffs in either of his two full seasons with the club, ranking second-last in the Eastern Conference in 1995-96 and 1996-97.  Bertuzzi's playing style as a power forward resulted in comparisons to former Islander Clark Gillies. As a result, the club hired Gillies to personally mentor Bertuzzi. Failing to meet lofty expectations from the club, Gillies once said of Bertuzzi, "If you're built like a freight train, you can't drive around like a Volkswagen." Feeling burdened with the pressure of playing up to the club's expectations while his offensive production diminished, he requested to be traded away at one point during the 1996-97 season. In response, Milbury, who had also taken over general manager duties the previous season, demoted Bertuzzi to the Islanders' minor league affiliate, the Utah Grizzlies of the International Hockey League (IHL). Playing 13 games in the minors, he registered 10 points before being called back up to the NHL. During the 1997-98 campaign, he continued to score below his pace as a rookie. On February 6, 1998, he was traded along with defenceman Bryan McCabe and a third-round selection in the 1998 NHL Entry Draft (Jarkko Ruutu) to the Vancouver Canucks in exchange for veteran forward Trevor Linden. The deal was made prior to the NHL's roster freeze in preparation for the 1998 Winter Olympics.  Bertuzzi and McCabe had both been widely regarded as the players of the future for New York after their respective drafts in 1993. While Milbury expressed regret at having to trade McCabe, relations between Bertuzzi and the club were strained. Welcoming the trade, Bertuzzi commented that "things weren't working out [in New York]."

Question: Tu Youyou (Chinese: Tu You You ; pinyin: Tu Youyou; born 30 December 1930) is a Chinese pharmaceutical chemist and educator. She is best known for discovering artemisinin (also known as qinghaosu) and dihydroartemisinin, used to treat malaria, which has saved millions of lives.

Tu Youyou was born in Ningbo, Zhejiang, China on 30 December 1930. She attended Xiaoshi Middle School for junior high school and the first year of high school, before transferring to Ningbo Middle School in 1948. From 1951 to 1955, she attended Peking University Medical School / Beijing Medical College. Tu studied at the Department of Pharmaceutical Sciences, and graduated in 1955. Later Tu was trained for two and a half years in traditional Chinese medicine.  After graduation, Tu worked at the Academy of Traditional Chinese Medicine (now the China Academy of Traditional Chinese Medical Sciences) in Beijing. She was promoted to a Researcher (Yan Jiu Yuan , the highest researcher rank in mainland China equivalent to the academic rank of a full professor) in 1980 shortly after the Chinese economic reform began in 1978. In 2001 she was promoted to academic advisor for doctoral candidates. Currently she is the Chief Scientist in the Academy.  As of 2007, her office is in an old apartment building in Dongcheng District, Beijing.  Before 2011, Tu Youyou had been obscure for decades, and is described as "almost completely forgotten by people".  Tu is regarded as the Professor of Three Noes - no postgraduate degree (there was no postgraduate education then in China), no study or research experience abroad, and not a member of any Chinese national academies, i.e. Chinese Academy of Sciences and Chinese Academy of Engineering. Up until 1979, there were no postgraduate degree programs in China, and China was largely isolated from the rest of the world. Tu is now regarded as a representative figure of the first generation of Chinese medical workers since the establishment of the People's Republic of China in 1949.

Answer: 

Some context: Hans Lundgren was born on 3 November 1957 in Spanga, the son of Sigrid Birgitta (nee Tjerneld), a language teacher, and Karl Johan Hugo Lundgren, an engineer and economist for the Swedish government. He lived in Spanga until the age of 13, when he moved to his grandparents' home in Nyland, Angermanland. Some sources wrongly state 1959 as his year of birth, but Lundgren himself has confirmed it to be 1957. He has two sisters and an older brother; he was raised in the Lutheran church.
Lundgren resides in Los Angeles, California. He speaks Swedish and English, as well as smaller amounts of French, German, Italian, Japanese, and Spanish, but is not fluent in five languages as has often been reported.  He is an avid football fan. He supported Everton FC when he lived in Europe, but developed more of an interest in international football tournaments (such as the UEFA European Championship and the FIFA World Cup) after moving to Los Angeles.  During the 1980s, Lundgren had relationships with Jamaican singer Grace Jones and American model Paula Barbieri. In 1994, he married Anette Qviberg, a jewellery designer and fashion stylist, in Marbella. The couple decided they liked Marbella so much that they rented accommodation there for years, before eventually buying a family home there. They have two daughters: Ida Sigrid Lundgren and Greta Eveline Lundgren, both born in Stockholm. Lundgren and Qviberg have cited the reason for living away from Hollywood is that they want to give their children as normal a childhood as possible. His father died in 2000.  In early May 2009, Lundgren's Marbella home was reportedly broken into by three masked burglars who tied up and threatened his wife, but fled when they found a family photo and realized that the house was owned by Lundgren. Lundgren later stated he believed the intruders to be Eastern European and had asked contacts in Bulgaria to investigate them, but to no avail. After the incident, Lundgren's elder daughter, Ida, suffered from PTSD. His wife was the "most traumatized", and as of 2011, they are divorced.  Lundgren currently lives in Los Angeles, California. He broke up with his girlfriend, Jenny Sandersson, in 2014 and it was said that they were secretly engaged and married later.
