Allen Hazen
Allen Hazen (1869–1930) was an expert in hydraulics, flood control, water purification and sewage treatment. His career extended from 1888 to 1930 and he is, perhaps, best known for his contributions to hydraulics with the Hazen-Williams equation. Hazen published some of the seminal works on sedimentation and filtration. He was President of the New England Water Works Association and Vice President of the American Society of Civil Engineers.
==Early life and education==
Allen Hazen was born in 1869 on his family farm located near the Connecticut River close to the small town of Norwich, Vermont. He attended the New Hampshire College of Agriculture and Mechanical Arts (which was affiliated with Dartmouth College) and graduated with a Bachelor of Science degree at 15 years of age.〔Brown, Edward S.

During a year spent at MIT (1887-8), Hazen studied chemistry and came into contact with Professor William T. Sedgwick, Dr. Thomas M. Drown and fellow students George W. Fuller and George C. Whipple.
