1873–1929
An early dairy expert and agricultural writer, this author focused on practical ways to improve milk quality, creamery methods, and the dairy industry in New Hampshire. His surviving works are concise, hands-on, and closely tied to the everyday problems of farming and food supply in the early 1900s.

by Clarence Bronson Lane, (Ivan Comings) Ivan C. Weld
Born in 1873, Ivan Comings Weld built his career around dairying at a time when milk production and public health were becoming more scientific subjects. Records from the New Hampshire College of Agriculture and the Mechanic Arts list him as an instructor in dairying, and several of his publications were issued through the New Hampshire Agricultural Experiment Station.
His writing centered on practical agricultural problems rather than literary fame. Works attributed to him include The Care of Composite Milk Samples, The Babcock Test for New Hampshire Farmers, and studies of the dairy industry in New Hampshire. He also co-authored A City Milk and Cream Contest as a Practical Method of Improving the Milk Supply, reflecting his interest in improving dairy standards and milk quality.
Weld died in 1929. Today, he is remembered mainly through these agricultural bulletins and technical works, which offer a clear glimpse into the everyday science of dairying in the early twentieth century.
