It's not every day your school gets a visit from a timelord, but last April that's exactly what happened at Wycombe high school. Former Dr Who Colin Baker materialised to talk to pupils about his love of science fiction literature in a special event organised by librarian Catherine Kirk.
Catherine might not be able to traverse galaxies, but she is always willing to go the extra mile, according to French teacher Jenny Black, who nominated her for our chocolates, champagne and flowers.
"She is absolutely marvellous and always goes out of her way to help staff and students," says Jenny. "She has organised some super lunchtime activities and talks."
Catherine enjoys helping the school's 1,400 girls to look beyond the curriculum and to expand their knowledge of more unusual subjects using the library's resources. Everything from Caribbean patois to origami have been the subject of discussion and demonstration in Catherine's lunchtime sessions at the Buckinghamshire school.
But she's just as busy the rest of the day, acting as the helpful librarian - every teacher and pupil's best friend.
"As teachers, we are always busy and she is really good at thinking of ways in which she can help," says Jenny. "If ever we want any information she is brilliant at getting hold of extra resources."
Last July Catherine turned the library into a veritable biblioth que to accommodate Jenny's special French-themed Bastille Day project, with displays, quizzes and competitions on subjects as diverse as postage stamps, the Channel Tunnel and impressionist paintings.
"She has transformed our library over the years into a welcoming, cosy area conducive to study and research," says Jenny. "She goes far beyond the call of the run-of-the-mill librarian."
Heroes are out there, but we need you to reveal them in all their glory.
Think of the person in your school - teacher, classroom assistant, governor, cook - who always goes the extra mile. Then tell us about them in a letter or email to Sarah Bayliss at the address above. Go on, they deserve recognition. (Flowers kindly supplied by Marks Spencer.)
