Who was Henry Jardine Bidder?
Reverend Henry Jardine Bidder was an Alpine gardener and a fellow of St. John's College, Oxford. He was active in the late-19th and early-20th centuries and his work is known to have influenced both Reginald Farrer and Ellen Wilmott. In the early 20th century a rock garden was added in the northwest corner by the Bursar, Henry Jardine Bidder, aided by the well-known botanist R.J. Farrer. This was remodelled in 1986.
