Having started as a child actor – first appearing on screen aged seven – Richard O’Sullivan, who has died aged 82, went on to a major TV career playing still relatively youthful characters, representative of the social and sexual freedoms that grew from the liberations of the 1960s.
Between 1972 and 81, he appeared in more than 100 episodes of peak-time ITV comedies as funny, frisky men in their 20s and 30s. The first of these was Dr Lawrence Bingham in the hospital sitcom Doctor in Charge, radiating a cheeky charm that led to his career-defining casting as Robin Tripp in Man About the House, in the mid-70s and its spin-off, Robin’s Nest, a few years later.
