This special issue has been sponsored by GASAT 12, the last international conference of the Gender and Science and Technology Association in memory of Dr Jan Harding (1925-2018)


Jan was a founder member of GASAT in 1981, was known as the ‘Mother of GASAT’ and was co-convenor, with Dr Barbara Hodgson, of the last conference. As a young science teacher, she became concerned about gender issues in science education and went on to contribute to many major initiatives in the field both in the UK and worldwide. She was a highly valued teacher and colleague, a wonderful mentor and friend, and an inspiration to many working on gender and STEM issues all over the world.
