Lily Monique de Carvalho Marinho (May 10, 1921 – January 5, 2011) was a Brazilian television arts patron, philanthropist and socialite. Marinho, the widow of media mogul and Rede Globo founder Roberto Marinho, served as a UNESCO Goodwill Ambassador for peace beginning in 1999.
Marinho was born Lily Monique Lemb in Cologne, Germany, on May 10, 1921. She was the only daughter of British soldier John Lemb and his French wife, Jeanne Bergeon. She was born in Germany because her father was stationed in the country during the post-World War I period. However, she was raised in Paris. During her life, Marinho would be married to two of Brazil's wealthiest men - Horacio de Carvalho and Roberto Marinho, who both owned newspapers. Her second husband, media mogul Roberto Marinho, died in 2003.
