Christine Lagarde Instagram – Commitment. Conviction. Courage. Three qualities that have come to define my friend Janet Yellen. Her hard work and dedication led her to many firsts: ▪️The first woman to be appointed as Secretary of the Treasury ▪️The first woman to serve as Federal Reserve Chair ▪️Including the Council of Economic Advisers, the first person to hold the Big Three macroeconomic policy positions in the US My dear Janet, it has been a delight to work alongside you over the years.
