The Royal Academy of Engineering (RAEng) has hung portraits of three Women of Outstanding Achievement, donated by the UK Resource Centre for Women in Science Engineering and Technology (UKRC).
The portraits are of Dr Joanna Kennedy, Professor Julia King and Professor Wendy Hall, all fellows of the academy.
The portraits are part of the UKRC's Women of Outstanding Achievement Photographic Exhibition collection and have been donated to RAEng to provide inspiration to future generations of women in the field.
Now in its fourth year, the exhibition profiles pioneering women in science, engineering and technology (SET) as role models in a sector in which females are under-represented.
Impressed with the impact of the UKRC initiative, the Women into Science and Engineering (WISE) Campaign has commissioned a further portrait of its founder chair and patron, Baroness Platt of Writtle, to celebrate its 25th anniversary - her portrait will also hang at the academy.
Dr Joanna Kennedy was part of last year's exhibition and was chosen for her leadership and inspiration to others in civil engineering as director of engineering firm Arup.
In 2007, Professor Julia King was also named Woman of Outstanding Achievement for leadership in her research career and role as managing director of fan systems at Rolls Royce.
Professor Wendy Hall is a computer scientist and was the first female senior vice-president of RAEng.
She was profiled in the 2006 Women of Outstanding Achievement exhibition for discovery and innovation.
The donation of the portraits is part of a diversity and engineering campaign which the UKRC has been working closely with RAEng to develop.
The UKRC has developed an extensive programme which the academy can use to: review its policy and practise in implementing equality and diversity; identify best practice within similar bodies; and develop an action plan to deliver an integrated diversity strategy.
This has included training, focus groups and the establishment of a Diversity Working Group, chaired by Professor Wendy Hall.
This year's portraits will be unveiled at the Wellcome Conference Centre, Euston Road, London.
They will include ecological builder, Barbara Jones; founder and chief executive of one of Britain's fastest growing IT companies, Ann Budge; and outreach officer for the Institute of Astronomy, Carolin Crawford.
Following the event, the photographs will also be given to a relevant company, university or professional institute on permanent loan to ensure the exhibition has a lasting impact.
