Sir Angus Deaton from Princeton University and Cambridge University’s Richard Henderson visited the classrooms at Hawick High School.
They met pupils and teachers to discuss their academic journeys.
Head teacher Vicky Porteous said: “For me, meeting my favourite scientists is an absolute thrill.”
Both men were born in Edinburgh but moved to the Borders during their childhoods, attending primary in Newtown St Boswells and Newcastleton, before going to Hawick High.
Sir Angus was awarded the Nobel Prize in 2015 for his work in economic sciences.
