Bob is a National Geographic photographer who spends some time at Karisoke. Fossey notes that Bob "thoroughly" documents the end days of Coco and Pucker's time at Karisoke. Fossey says that many of her guests are unwelcome, but that Bob takes time to teach the staff how to work on the lanterns - a task that's particularly important and that few people know how to figure out, especially with the fact that there are no parts available.
