The bequest was made by the late Miss Ella Rose Curtois, who spent most of her life in Paris, and the opening ceremony was perfromed by her first cousin, the Rev. Peregrine Arthur Curtois, now living in semi-retirement at Ipswich.
The new wing provides additional exhibition space as well as much needed storage accomodation and room for working on the restoration of paintings.
Presiding, the chairman of the Lincoln Library, Museum and Art Gallery Committee, Councillor W. J. Bell, said that Mr. Curtois was born at Northgate Cottage, Lincoln. He was admitted to the freedom of the city in 1914, as was his father before him.
"This day, I am quite sure, will become quite a memorable day for me," he said. "When I took charge of the committe, and knew the full details of the bequest, I dreamed that an extension could be made."In his address, Mr. Curtois said the new wing added yet another gem in the architectural beauties in Lincoln.
Mr Curtois spoke of the family tree, and said that his godfather was the Rev. Algernon Curtois, who was ordained in Lincoln Minster, but owing to an accident at college, he took no livings. He lived in Lincoln helping the church for 30 years.
"He will be remembered for his gallant fight with others to save St. Benedicts from destruction, and, without success, St. Peter-at -Arches," he said.Ella Rose Curtois, he said, devoted herself to sculpture. "She must have learned this from her father, the Rector of Branston, who lived at a house called Long Hills, about halfway between Branston and Potterhanworth.
Recalling his early days in Lincoln, Mr. Curtois said his strongest recollection was of the Minster, where he used to insist on being taken as a child."Of the people in the Cathedral, I do remember very well Bishop Edward King, who is one who is rightly revered as a Saint today."
Mr Curtois added: "I have the warmest place in my heart for the City and County of Lincoln."
He went on: "In modern times, Lincoln has made a remarkable job in that they have retained all the interesting parts - it is still Old Lincoln - but we have our own modern development which caters for our residents and will cater better for visitors as the years go by."Main contractors for the building were H.
