Monika Dannemann was the daughter of a german industrialist, a professional figure skater and artist.
The following biography of Monika Dannemann is from Wikipedia:
Dannemann was first introduced to Jimi Hendrix on 12 January 1969, in Düsseldorf, after being invited to a Jimi Hendrix concert there. She spent that night with him and part of the next day too, when she accompanied him to his next concert in Cologne; after that, she returned to Düsseldorf. He spent the last night of the tour with famous model and "scenester" Uschi Obermaier, with whom he was filmed kissing and petting outside the Kempinski Hotel the next morning. He wrote to Dannemann on 25 March 1969, inviting her to visit him in New York City. Dannemann claims she next saw Hendrix when she travelled to London on 25 April 1969 in the hope of meeting him again, where she bumped into him at the Speakeasy Club. She says they spent some time together over the next nine days, but she only spent one night with him.
After his September 1970 European tour, Hendrix began a relationship with the Danish model Kirsten Nefer. (It was reported in the Danish press at the time that they were engaged.) After Nefer left London due to work, he again took up with Dannemann on 15 September and spent the next four nights at her flat at the Samarkand Hotel, Notting Hill Gate, where he died.[2]
During this last visit, Dannemann claimed that Hendrix had asked her to marry him, and she said she would have done so if he had not died. Dannemann is known for being the last person to have seen Hendrix alive. On the evening of 17 September Hendrix took at least one amphetamine pill (known as a "black bomber") at a party, where he stayed for a short while. Later, at Dannemann's flat, Hendrix took nine of her Vesparax sleeping tablets; the recommended dose was 1/2 to 1 tablet. Dannemann stated that on the morning of 18 September 1970, she found Hendrix in a coma at her basement flat. She called for an ambulance which arrived at 11:27 AM. Hendrix was officially declared to have died at St. Mary Abotts hospital at 12:45 PM. The cause of death was asphyxiation through aspiration of vomit due to a barbiturate overdose.[3]
