Ben Gundersheimer (bengundersheimer.com, MisterGsongs.com) is a Latin GRAMMY Award-winning artist, author and educator. Hailed as "a bilingual rock star" by The Washington Post and "irresistible" by People magazine, he was originally dubbed MISTER G by his young students while pursuing a Master of Education degree. Senorita Mariposa is his first picture book, based on a song on his album Chocolalala. He is also the author of How Many Squirrels Are in the World?, based on a song from his album Pizza for Breakfast, and Lilah Tov Good Night, based on a song from his album The Mitzvah Bus. MISTER G tours internationally, performing in venues such as Lollapalooza, Austin City Limits, New Orleans Jazz Fest, and the Metropolitan Museum of Art. His dynamic, interactive bilingual performances aim to dissolve borders and foster cross-cultural connections. He lives in the woods of Western Massachusetts with his wife, Katherine, rescue mutt, Josie, and cat, Chloe Bird.
