Steven Edwards, who waged litigation battles for banks, health care companies and other corporate giants at Quinn Emanuel Urquhart & Sullivan and Hogan Lovells, died Wednesday after contracting COVID-19, the disease caused by the new coronavirus, Quinn Emanuel said. He was 73.

His death comes a month after Quinn Emanuel said an unnamed lawyer at the firm—identified as a partner in New York—had tested positive for COVID-19, leading to the closure of its Manhattan office earlier than most firms. Representatives for the firm did not answer whether Edwards’ case was related to the earlier diagnosis.
