Most Important Contribution:
Jenney's greatest fame came from his large commercial buildings. His Home Insurance Building in Chicago was one of the first buildings to use a metal skeleton for support. It became the standard for American skyscraper design. Jenney's skeleton-frame Manhattan Building was the first to achieve a height of 16 stories. His Horticultural Building was the largest botanical conservatory ever built.
Student draftsmen who learned from Jenney included Daniel H. Burnham, Louis Sullivan, and William Holabird. For this reason, Jenney is considered the founder of the Chicago School of architecture, and the father of the American skyscraper.
