Question: The author the "Breaking the Surface" won Summer Olympic gold medals in which years?
Context: Michael Fred Phelps II (born June 30, 1985) is an American former competitive swimmer and the most decorated Olympian of all time, with a total of 28 medals.  Phelps also holds the all-time records for Olympic gold medals (23), Olympic gold medals in individual events (13), and Olympic medals in individual events (16).  In winning eight gold medals at the 2008 Beijing Games, Phelps broke fellow American swimmer Mark Spitz's 1972 record of seven first-place finishes at any single Olympic Games.  At the 2004 Summer Olympics in Athens, Phelps had already tied the record of eight medals of any color at a single Games by winning six gold and two bronze medals.  At the 2012 Summer Olympics in London, Phelps won four gold and two silver medals, and at the 2016 Summer Olympics in Rio de Janeiro, he won five gold medals and one silver.  This made him the most successful athlete of the Games for the fourth Olympics in a row. Nikolai Yefimovich Andrianov (Russian: Николай Ефимович Андрианов , 14 October 1952 – 21 March 2011) was a Soviet/Russian gymnast.  He held the record for men for the most Olympic medals at 15 (7 gold medals, 5 silver medals, 3 bronze medals) until Michael Phelps surpassed him at the 2008 Beijing Summer Olympics.  Andrianov is the third athlete (male or female) in cumulative Olympic medals after Phelps's 28 and Larisa Latynina, who earned 18.  Andrianov won the most medals at the 1976 Summer Olympics with 6 individual medals and one team medal.  Within the sport of Men's Artistic Gymnastics, he also holds the men's record for most individual Olympic medals (12) and shares the male record for most individual Olympic gold medals in gymnastics (6), tied with Boris Shakhlin and Dmitry Bilozerchev (the latter of which only if you count the 1984 Alternate Olympics).  In many other rankings among all-time medal winners at the Olympic, World, and European levels, he ranks very high, (for example, he is second only to Vitaly Scherbo in total individual medal counts at either the gold level or any level at the combined Olympic and World levels as well as at the combined Olympic, World, and European levels) – easily making him one of the most decorated gymnasts of all time.
