The Kaliapparat or potash bulb, invented in 1831 by German chemist Justus von Liebig (1803 – 1873), is one of the most important chemistry vessels and analytical tools in history. The interconnected glass spheres were used for the analysis of carbon of organic compounds. The importance of the kaliapparat led to its use as a symbol of innovation for the American Chemical Society.

The American Chemical Society

Founded in 1876 and chartered by the United States Congress, and currently with more than 154,000 members, the nonprofit American Chemical Society (ACS) is the world’s largest scientific society. Our mission is to advance the broader chemistry enterprise and its practitioners for the benefit of Earth and its people. Our vision is to improve people’s lives through the transforming power of chemistry.

The ACS is one of the world’s leading sources of authoritative scientific information. It is at the forefront of the evolving worldwide chemical enterprise and the premier professional home for chemists, chemical engineers, and related professions around the globe.

The Midland Section

On December 8, 1919, the Midland Section of the American Chemical Society was founded in Midland, Michigan. The Section now serves Midland, Bay, Saginaw, Gratiot, and Isabella Counties.

According to the National Charter (H.R. 7709, effective January 1, 1938) which incorporated the American Chemical Society, “The objects of the Midland Section include the following:

  • Encourage in the broadest and most liberal manner the advancement of chemistry in all its branches
  • Promote research in chemical science and industry
  • Improve the qualification and usefulness of chemists through high standards of professional ethics, education, and attainments
  • Increase and diffuse chemical knowledge
  • Promote scientific interests and inquiry…”

To this end, the Midland Section has numerous programs not only for ACS members, but also for students, educators, and the wider community.

Midland in 1919

To better understand the influence of chemistry on Midland, researchers investigate the historical context of when the section was founded. The chemical industry in Midland was beginning to develop in 1919 amidst a backdrop of great local and national change. The citizens of Midland in 1919 were recovering from World War I and the flu pandemic of 1918, prohibition was a year away, and states were beginning to vote on women’s suffrage. The population of Midland was around 5,400. Although in 1919 Midland was still a small, budding community, it soon would grow to be one of the largest and most important chemical production centers in the world.
