A failed chemistry exam & a Nobel for DNA repair: What Tomas Lindahl’s story tells us

Once failed in high school chemistry due to a teacher’s judgement, Tomas Lindahl later reshaped the same discipline. Awarded the 2015 Nobel Prize in Chemistry for his pioneering DNA repair research, Lindahl’s journey from classroom setback to scientific distinction highlights how early academic assessments can misjudge potential—and why education must look beyond grades to recognise long-term talent.
