Axel Emmermann (b. 1953) was the only person to alert U.S. authorities of an international e-mail sale offering of lunar material. His actions resulted in the recovery of stolen Apollo lunar rock samples and the arrest and conviction of four individuals for the theft. The name was suggested by E. K. Gibson.
