In page Tessa Wheeler:

"

Tessa followed her husband Mortimer to Cardiff in 1920 when he took up a post at the National Museum of Wales. She was the Keeper of Archaeology at the National Museum of Wales where her husband was promoted and held the position of Director from 1924 to 1926.[1] They undertook excavations together at Segontium in 1921–22 and at Gaer in 1924–25, working as a team. Tessa organised the excavations, controlled finances, and recorded the finds, and Mortimer interpreted the results.[1] They were preparing an excavation at Caerleon in 1926 when Mortimer was appointed Keeper of the London Museum. The family moved to London, but Tessa undertook the excavation on her own in the winter of 1926–27.[citation needed]
