William Sinclair ferts and chems category controller Steve Chalk has died aged 52. He was diagnosed with melanoma skin cancer two years ago.
Sinclair retail MD Danny Adamson said: "Steve will be hugely missed as he was such a lovely, warm and inspirational person."
Chalk had been at Sinclair for three years and was previously operations director at Growing Success Organics, part of Monro/Wessex Horticulture, for 13 years.
Before that he served in the British Army, 14th/20th Kings Hussars regiment, in both Europe and Iraq.
During his illness he raised awareness of melanoma by forming a fundraising group, #somethingsillyinjune, to raise proceeds for Factor 50 – the leading charity supporting skin cancer patients.
The group raised about £22,000 for Factor 50 over the past two years.
A memorial service is being held for Steve in Broad Chalke Parish Church on Friday, August 23, at 2.30pm and people attending are asked to wear bright colours.
