Pouring the brew is Mr. William F. Nolker, President, and to the far right, my great grandfather, Master Brewer, Louis T. Brinckwirth. There is someone missing in this photograph; the matriarch of the brewery and its most prominent families; Louis Brinckwirth's mother and Mr. Nolker's mother-in-law, Mrs. Fredericka Brinckwirth.
