She is said to have belonged to the "silk stocking set," but Della Cochrane Lamb spent most of her life working with those less fortunate than herself. Della began channeling her abundant energy and talent into community service in 1897, when she was still a teenager. That year, Melrose Methodist Church Auxiliary opened a day nursery on Fifth Street. One of the first day care centers in Kansas City, it looked after the children of immigrant north side families so that their mothers could work. When the Fifth Street nursery evolved into the Institutional Neighborhood House in1906, Lamb became president of its board of directors. She remained president for 27 years.
