Calvo was also an academic adviser in Butler College, where he regularly participated in the Spanish language table and was, according to Butler Director of Studies Matthew Lazen, “the sweetest man you could ever meet.” Molly Bagshaw ’13, a former student of Calvo and one of his Butler advisees, explained that Calvo stood out because of his passion and dedication. “Antonio had a huge impact on me, in terms of both my academic career and love of the Spanish language,” Bagshaw said. “If it weren’t for his advice and counseling, I probably wouldn’t be pursuing a certificate in the department or going to Peru this summer, two things I am extremely excited about.” During his time as director of Princeton in Spain, Calvo also grew close with many students who said he was one of the best parts of their experience abroad. “He really treated his students like human beings, and he really made the effort to understand us as young people,” said Phyllis Heitjan ’11, who attended the summer program with Calvo several years ago.
