Art history instructor Monica Bowen is the author of Alberti's Window, a blog designed to engage members of the general public, along with art students and art historians, with a number of fascinating and hidden tidbits and stories about art history. Bowen's frequent posts highlight a wide variety of lesser-known anecdotes about famous artists. Her most recent post, for example, explores the contentious relationship between painter Oskar Kokoschka and Adele Astaire - the older sister of Fred and an accomplished dancer in her own right. Kokoschka asked Adele to sit for a portrait that Fred Astaire and Bowen both agree was "a hideous mess." Other recent posts include an examination of Grace Kelly's collages comprised of pressed flowers and exploration of three specific times when paintings by Barnett Newman were slashed.
