Bob Owen, Croesor.

Robert Owen, O.B.E., M.A., better known as Bob Owen Croesor was an antiquary and book-collector from Llanfrothen, Merionethshire. Born in 1885, he was employed as a farm labourer and later as a clerk at the Parc and Croesor Slate Quarry. He became a lecturer with the Workers Educational Association and was also a popular radio broadcaster.

His interests lay in local history and Welsh genealogy. He collected manuscripts as well as books, and transcribed parish records. Although an advocate of the study of local history, his own topics of research were far reaching. He was an authority on the history of the Welsh in America in particular.
