In addition to Macron promising to launch an immediate fundraising campaign, French philanthropists pledged donations totaling 700 million euros to rebuild Notre Dame Cathedral. 

Bernard Arnault, head of LVMH; François-Henri Pinault, CEO of Kering; and L'Oreal's Bettencourt Meyers family promised a combined 500 million euros on Tuesday. The University of Notre Dame will also donate $100,000 to the cathedral's relief, and it said the campus basilica's bell would toll 50 times at 6 p.m. ET Tuesday.
