Delma Dorothie Kollar (née Lowman; 31 October 1897 – 24 January 2012) was an American supercentenarian. At the time of her death, she was the fourth oldest living person in the world, behind Besse Cooper, Dina Manfredini, and Jiroemon Kimura. She became the oldest person ever to be born in Kansas on 14 July 2010, surpassing the previous record of 112 years, 255 days set by Flossie Page in February 2006. On her last birthday, she became one of only 88 people to have attained the age of 114. Before recent research, she was thought to have been born in 1898. This was proved to have been wrong, based on the data in the census closest to her date of birth and proof that her younger sister was born in February 1899.
