John de Lancie
de Lancie, John Sherwood, Jr.
March 20, 1948 – present
Birth place: Philadelphia, Pennsylvania, USA
Wikipedia stated the day of birth as 1948-11-13 at one time, which may be based on a twitter post photo on 2018-11-13 showing him with a cake for his 70th birthday. However, he states that this photo was taken 'recently' and SFE3 states the date used here, since we found that source more reliable in many cases.
