Background and family life
Thompson was born in Whitehouse, County Antrim, the daughter of James Thompson, a Belfast linen merchant. Her uncle was the naturalist William Thompson. She described her childhood as "amphibious"; her family home was at Macedon Point and she frequently explored the coastline with her brother in a small boat. She spent three years in Dresden, Germany, then studied art at the Belfast Government School of Art, beginning in 1870, and later in London.
In 1900, she married Swiss artist Rodolphe Christen. The couple later moved to Scotland.
Geology
An active member of the Belfast Naturalists' Club, Thompson organised lectures and practicals, showing a particular interest in stratigraphy and petrography. Her original fieldwork mostly concerned sources of material in the glacial deposits of northern Ireland.
She was a friend and collaborator of northern Irish geologist Mary Andrews, and together they worked on glacial erratics, collecting samples, mapping and naming erratics with the aim of finding out the direction of ice flow in Ulster. As the secretary of the Belfast Field Club, her reports were published in the club's Proceedings.
In 1894, Thompson was elected to the Glacialists' Association.
Some time between 1907 and 1910, Thompson discovered a piece of Ailsa Craig microgranite at Moys, near Limavady, County Londonderry. The granite erratic showed the westernmost extent of the Irish Sea Glacier, as it had been carried south by the glacier from Scotland and its incorporation into glacial sediments allowed the route of the glacier to be mapped. Thompson's discovery placed the western limit of the glacier 20 miles (32 km) further west than its previous designation.
Art
Thompson won many prizes for her art, and was a member of the Belfast Ramblers' Sketching Club and the Belfast Art Society, of which she became patron in 1921.
Death
Madame Christen passed of heart failure at Llandudno in July, 1923.
