Historically, ~80% of justices have already been older than that when they join the court; Curtis's distinction may stand the test of time.
As of today, Justice Barrett has served on the Supreme Court for 2183 days. She passes Justice Benjamin Robbins Curtis (October 10, 1851-September 30, 1857) to have the 95th-longest Supreme Court tenure.
