Samuel Jay Crumbine (September 17, 1862 – July 12, 1954) was a pioneer in public health who campaigned against the common drinking cup, the common towel, and spitting in public in order to prevent the spread of tuberculosis and other germs.[1]

Crumbine was born at Emlenton, Pennsylvania on Sept. 17, 1862, the son of Samuel D. Crumbine and Sarah (Mull) Crumbine, both natives of Pennsylvania. His mother was of German and English descent; his father, who was of German descent and a mechanic, served in the Union Army during the American Civil War as a member of the One Hundred and Third Pennsylvania infantry, being first sergeant of Company H. He was captured by the Confederates and confined in Libby prison, where he died of sickness, his death occurring prior to the birth of his son, Samuel. The mother of Crumbine died in Pennsylvania, in 1902, aged sixty-two years.

At the age of twenty-one, Crumbine entered the Cincinnati College of Medicine and Surgery, where he worked his way through and graduated in 1888. Upon receiving his diploma, he moved to Kansas and engaged in the practice of his profession at Dodge City. While there, he was appointed to the State Board of Health by Gov. W. E. Stanley. Then on Sept. 1, 1911, he assumed the duties of Dean of the School of Medicine of the University of Kansas. Dr. Crumbine was married Sept. 17, 1890, his twenty-eighth birthday, to Miss Catharine Zuercher, of Cincinnati, Ohio. They had two children: Warren, born Jan. 29, 1892, and Violet, born March 5, 1896.
