She was born on a farm in Kilmalcom, Scotland and said the arrival of electricity at the farmhouse was the biggest change in her lifetime.
Mrs Brown also attributes her age to a positive attitude and inquiring mind.
'Smaller world'
The former teacher said: "The world has become a smaller place for the young with all the opportunities to travel.
"But I'm not sure that I would have been adventurous enough if it had been available in my time."
She said everything should be taken in moderation apart from family and friends.
"A sense of humour is important and trying to stay positive," Mrs Brown added.
12 great-grandchildren
Mrs Brown spent most of her life in Guildford where she moved after meeting and marrying her husband John.
She has played an active part in the local community, distributing powdered milk and orange juice to mothers and babies during World War II.
Following the death of her husband in 1950 she took over his position on the Guildford Rural District Council.
Her 78-year-old son George, five grandchildren and 12 great-grandchildren helped mark her milestone at the Eastlake Residential Home in Godalming where she now lives.
