Extract from Chapel Centenary Article 2

 

"He married a farmer’s daughter, Sarah Kitchen, and it was to their youngest son that they gave him Kitchen as a Christian name. The name William Kitchen Parker was known by every scientist and man of of eminence in Great Britain. He was educated at King’s School, under the headmastership of the Rev. William Cape. He started his career as an apprentice to a druggist named Woodroffe at Stamford. He ultimately became a famous surgeon, was Hunterian Professor of Anatomy and Phsychology of the Royal College of Surgeons, and a Fellow of the Royal Society. The science of the world today is the richer for his researches on the Foraminifera and on the Vertebrate Skeleton, and for his learned writings. Like so many great scientists he was an intensly religious man and it has been said of him “from his fifteenth year to his death he kept undimmed by illness or sorrow an abiding sense of the Divine presence. He died on the third day of June 1890, and was buried by the side of his wife in Wandsworth Cemetery."
