Matthew von Ertfelda is a contestant from Survivor: The Amazon. Known for being the "student" of skilled strategist Rob Cesternino, Matthew knew little about the game but his physical strength and likability made him an asset around camp although at times his tribe mates would grow concerned about his "crazier" behavior, such as his obsessive sharpening of the machete. Eventually, with Jenna Morasca winning the late game Immunity Challenges, Rob's teachings would backfire as Matthew formed a Final Two alliance with her, ultimately getting him to the end where he'd become the first finalist to lose in a landslide vote.
