Mike Bartlett writes: I was very sorry to hear of the passing of Gervase Markham. He was an inspiration to many, and my thoughts and prayers are with his family and friends. The Revd Peter Ould’s excellent obituary (Gazette, 24 August) implied that he had been employed only by Mozilla. I knew him as a colleague at Metaswitch (formerly Data Connection), in Enfield. If memory serves, I believe he split his time between the two employers for at least some of this period.

Canon John Rankin writes: The Ven. Martin Badderley (Gazette, 13 July), tutored me in Old Testament studies at Fitzwilliam College, when he was chaplain there. I enjoyed his tutorials, but more especially when he came to my rescue after I left an examination prematurely. I bumped into Martin and he asked me what I was up to. After my explanation, he sorted it all out with the examiners and all was well: his humane response to a student’s predicament. I have always remembered him with gratitude for his pastoral skills.
