AB Crookall was born in Blackpool 1873 and moved to the island at the age of 13, the son of a boarding-house proprietor. He was a builder, decorator and restauranteur, before winning the contract during WWI to feed internees at Knockaloe. By the end of the war he was the one of the richest men on the island, going on to be elected to the House of Keys in 1921, and becoming Mayor of Douglas in 1922.
In 1927 he purchased a house on Desmesne Road and had it fitted as a maternity ward as a gift to the people of Douglas.
The new maternity home was named the Jane Crookall Maternity Home in memory of Jane Crookall, née Callow, who died in 1922.
