Commander Beverly Cheryl Crusher, MD, (née Howard) was the chief medical officer aboard the USS Enterprise-D and its successor, the USS Enterprise-E, both under the command of Captain Jean-Luc Picard. She briefly left her post as CMO of the Enterprise-D in 2365 to become head of Starfleet Medical, only to return the next year.
Beverly attended Starfleet Academy from 2342 to 2350. During this time, she became romantically involved with Jack Crusher after being introduced by their mutual friend, Walker Keel. It took months for her to realize their attraction. The two were married after Jack proposed to her through a gag gift, a book entitled How to Advance Your Career Through Marriage, and welcomed a son, Wesley Crusher, in 2348.
While was Jack serving aboard the USS Stargazer under Jean-Luc Picard, the couple became good friends with the captain. Beverly graduated in 2350, and interned with Dr. Dalen Quaice on Delos IV in 2352. In 2354, Jack died on an away mission, and Picard brought Jack's body home to the grieving Beverly and Wesley. Picard even accompanied her to see Jack's body in the morgue at Starbase 32, a gesture Beverly appreciated despite Picard's feelings that it would be better for her to remember him alive rather than as a corpse. Beverly never fully recovered from Jack's death.
Dr. Crusher took the bridge officer's test in 2362, and was promoted to commander. She was appointed chief medical officer of the Starship Enterprise-D in 2364, and joined the ship at Farpoint Station with Wesley, reporting aboard on stardate 41154. Picard initially had reservations about her presence, but she assured him that the past would have no effect on her duties and she had no problem serving under his command.
