She was portrayed by Gates Mcfadden.
Crusher was born on October 13, 2324 on Earth's moon to Paul and Isabel Howard. After the death of her parents she was raised by her grandmother Felisa Howard.
At the age of 18 Crusher embarked on a career in medicine, and attended Starfleet Medical Academy. Soon afterwards Crusher had fallen in love with Starfleet officer Jack Crusher, and married him in late 2348. The following year their son Wesley was born - about one year earlier than they planned.
Jack Crusher died in 2354, and his body was brought home to Beverly and Wesley by Jean-Luc Picard. After her husband's death Beverly left Starfleet for several years, going in to private practice in St. Louis before re-entering Starfleet in 2360.
In 2364 she was assigned to the USS Enterprise-D under Captain Jean-Luc Picard. At first the relationship was uneasy between Crusher and Picard, however they soon both became good friends. Meanwhile Wesley settled in to life on the Enterprise, and became an acting ensign while his application for the academy was considered.
Crusher left the Enterprise for a year in 2365 in order to take up a posting at Starfleet Medical. She was succeeded as CMO by Katherine Pulaski. Her son Wesley stayed on the Enterprise with her blessing. When Pulaski left the Enterprise Crusher rejoined the Enterprise crew in 2366, and remained on the ship until its destruction in 2371.
The following year she was assigned to the Enterprise-E with the rest of the senior staff and many former Enterprise-D crew mates. She was instrumental helping to defeat the Borg incursion into Earth's past.
Crusher briefly left the Enterprise in 2379 to again take up a position at Starfleet Medical, but later returned to the Enterprise.
