Anne McCaffrey (1926-2011) is one of the more prolific writers I know of.
I am mostly familiar with the “Dragonriders of Pern” series, and a part of the Acorna series.
At the Eurocon covention in Copenhagen, 2007, she was the main Guest of Honour, and the main reason I went to my first larger convention. At the reading she read from her story “The Ship Who Sang”, and that was a great convention experience. I still have to read more of the Brain Ship series, but there is so much to read/watch/listen to.
There is simply too much material to mention here, so I recommend visiting the Wiki page to get to know more about her work, but here are a few facts.
She was the first woman to win the Hugo award, voted by World Science Fiction Convention in 1968. This was with a novella of the Pern series, “Weyr Search”, later incorporated in the first Pern novel “Dragonflight”.
She was also the first woman to win the Nebula award in 1969, by the Science Fiction Writers of America. This was for her second Novella in the Pern series, “Dragonrider”, also later incorporated into the Dragonflight novel.
At the Eurocon she humorously told how she found having trouble handling the rocket shaped Hugo Award, because she found that it resembled a phallus symbol. Interesting how things have changed since then.

Also, at the convention she was very approachable at the table, and at the signing, where I got my hard cover copy of “The White Dragon” signed.

This was Anne McCaffrey’s last convention, ever, and I consider myself lucky to have met the author of one of my favourite book series, before she passed beyond the Rim.
Later I will tell more of my own experience with her work, a bit about the Acorna series, and in more detail, about the Pern series.
