Context: St. Bernard's is a Catholic High School in Furness, and is situated on Rating Lane in Barrow-in-Furness, Cumbria, England.  It was established in 1979, when the introduction of comprehensive education in the town resulted in a merger between the former St. Aloysius School (1953) and the Girls' Convent School (otherwise known as 'Our Lady's School', which had been operated by the nuns from Croslands Convent since 1929 ).  It was officially established as a 'Specialist Science' School in 2006.  The head teacher was Mr Eugene Tumelty who had been there for thirty years.  He retired at the end of the 2010-2011 School Year.  Mr Tumelty received the Benemerenti Medal for his religious teachings in the school.  The headteacher is currently Mrs P Croft.  The houses were named Campion, Fisher and Moore.  Due to the expansion of the school there are now four houses.

At some point (certainly before the opening of the Laboratory of Molecular Biology (LMB) in 1962) 'the Molteno' became the only totally contained MRC (Medical Research Council) unit in Cambridge (the MRC Biochemical Parasitology Unit), although the building was still rented from the University of Cambridge.  It is no longer extant as an MRC unit, but existed until 1987, after which time it became part of the University of Cambridge's Pathology Department.
