From Bulbapedia, the community-driven Pokémon encyclopedia.
Professor Alden (Japanese: ウメズ教授 Professor Umezu) is a character of the day who appeared in A Ruin with a View. He is an archaeologist who had his base in the Pokémon Center of Oldale Town as he studied the Oldale Ruins.
He showed Ash and May the nearby Oldale Ruins and informed them about the Pokémon that resided there. Suddenly, Team Magma members arrived and blackmailed Alden so that he could give them access to the ruins. He was then kidnapped by Team Magma. Ultimately, he succumbed to their threats and opened up a secret chamber of the ruins with the help of four colored orbs for the grunts to enter. Team Magma inspected the room and eventually left, dissatisfied with what they found, leaving Alden unharmed.
Ash and May arrived on the scene just too late and saw Team Magma escaping in a helicopter. Afterwards, Pikachu used Thunderbolt to send Team Rocket blast off, which helped recover the four keys. Professor Alden then placed the treasures inside a cubed stone within the stone chamber. This uncovered a hidden stairwell, which led to an underground lake filled with the prehistoric Pokémon Relicanth, something he found helpful for his studies on the relationship between ancient people and Pokémon.
He reappeared in Jessie's flashback in A Three Team Scheme!.
