Alessandra Giovannoni was born in Rome where, in the 1970s, she attended the Faculty of Architecture, and then enrolled at the Academy of Fine Arts, where she graduated in 1982 with Emilio Greco in sculpture, a technique that she soon left in favour of painting, more congenial to her own research focused on light and the instantaneous vision of reality. In the 1980s, she attended courses in engraving techniques at the Calcografia Nazionale, created set designs for several films and executed wall decorations for private homes and hotels in the capital.
Between 1986 and 1997, she was commissioned to paint portraits of Giuseppe Capogrossi (1986), Giacomo Perticone (1995), Augusto Del Noce (1995) and Antonio Rosmini (1997) on the occasion of International Study Conferences promoted and organised by La Sapienza University in Rome. Since 1983, she has participated in numerous group exhibitions; in 1986, she held her first solo exhibition at the Galleria Al Ferro di Cavallo in Rome, and in 1991, her collaboration with the Galleria Il Segno in Rome began. Over the years, his works have been acquired by the Municipal Gallery of Modern and Contemporary Art in Rome, the Avezzano Museum, the Museum of Sacred Art in San Gabriele al Gran Sasso, the Villa San Giovanni Museum and the Banca Nazionale del Lavoro for the Contemporary Art Collection. In 2001, he received a medal from the Mayor of Rome for the execution of an eight-colour silkscreen commissioned by the municipality. She has won numerous prizes (first prize at the fifth edition of the Kiwanis Prize and the XXVI Avezzano Prize, 1999; the prize for painting at the XIX International Erice Prize, 2000; second prize at the first edition of the Ferruccio Ferrazzi Prize; first prize at the LIX edition of the Michetti Prize, 2008); in 2005 she was invited to the XIV Quadriennale di Roma; in 2011 to the LIV International Art Exhibition, Venice Biennale and, in 2014, to the "Creative Art Biennale - Viterbo Biennale".
