Danny Dunn - Characters

Characters

• Professor Euclid Bullfinch, a researcher at the fictional Midston University. The professor was also a musician who played the bass viol (also known colloquially as the "bull fiddle"). He is plump and somewhat bald.
• Teenager (some books depicted an elementary school setting) Danny Dunn, who would always get into complicated problems involving the professor's latest invention. Danny is looking forward to a career in science, and admires Professor Bullfinch as a mentor.
• Mrs. Dunn, Danny's widowed mother, who was a live-in housekeeper for Professor Bullfinch.
• Teenager Irene Miller, Danny's friend and next-door neighbor. Irene's father taught Astronomy at Midston University. Irene was particularly interested in biology.
• Teenager Joe Pearson, Danny's friend. Joe was the poet of the group. He often functioned as an amusing sidekick to Danny, expressing bafflement at the complicated technology employed by Danny and the Professor.
• Teenager Eddie (Snitcher) Phillips, rival of Danny
• Doctor A.J. Grimes, a friend of Professor Bullfinch introduced in the first book, Danny Dunn and the Anti-Gravity Paint. Grimes is a curmudgeonly figure, rarely taking the teenagers seriously, and often trying to antagonize the Professor. Doctor Grimes was also a musician who played the piccolo; he and Professor Bullfinch would on occasion play duets. Tall and lanky, he is in many ways a contrast to his friend Bullfinch.
