Andrea Albert Pierre Casiraghi (born 8 June 1984) is the elder son of Caroline, Princess of Hanover, and her second husband Stefano Casiraghi. He is the eldest grandchild of Rainier III, Prince of Monaco, and American actress Grace Kelly. Casiraghi is currently fourth in the line of succession to the Monegasque throne, following his twin cousins and his mother. Family background and early life Casiraghi was born on 8 June 1984 at the Princess Grace Hospital Centre in La Colle, Monaco, to Princess Caroline of Monaco and her husband, the Italian businessman and athlete Stefano Casiraghi. The eldest grandchild of Rainier III, Prince of Monaco, and his wife, former American actress Grace Kelly, Casiraghi was named after his father's childhood friend, his maternal uncle Prince Albert and his maternal great-grandfather Prince Pierre, Duke of Valentinois. Casiraghi's godparents are his maternal aunt Princess Stéphanie and his paternal uncle, Marco Casiraghi. His sister Charlotte was born on 3 August 1986, and his brother Pierre on 5 September 1987. On 3 October 1990, Casiraghi's father died in a speedboat accident in Monaco. He was buried several days later in Monaco's Chapel of Peace. Princess Caroline did not know how to tell her children that their father had died, so her father, Prince Rainier, did so. To protect her children from excessive media attention, Caroline moved to Saint-Rémy-de-Provence, and later to Paris. In 1999, his mother married Ernst August, Prince of Hanover, and gave birth to Princess Alexandra of Hanover. Besides a half-sister, Casiraghi gained two stepbrothers, Ernst August, Hereditary Prince of Hanover, and Prince Christian of Hanover, through his mother's remarriage. Education and career Growing up mostly in France, Casiraghi earned his international baccalaureate in December 2002 from the International School of Paris, where his mother gave the commencement speech in June the following year, confirming that she was an ISP parent. Following a period at McGill University in Montreal, Quebec, Canada, he eventually graduated in 2006 with a B.A. degree in visual arts and international politics from the American University of Paris. He was an intern at the embassy from Qatar to Monaco, which, like most of Monaco's embassies, is based in Paris. In 2014, he started a Master of Business Administration at IE Business School (formerly known as Instituto de Empresa) in Madrid. Philanthropy and social activities Since 2004, Casiraghi has been involved, to varying degrees, with the World Association of
