Truman Heminway Aldrich (October 17, 1848 – April 28, 1932) was a civil engineer, a mining company executive, and a paleontologist, and briefly served in the United States House of Representatives and as Postmaster of Birmingham.

He attended public schools and a military academy at West Chester, Pennsylvania before enrolling at the Rensselaer Polytechnic Institute in Troy, New York.

He purchased the mines outright in 1875 and named the surrounding settlement Aldrich, leasing the operation to his younger brother William while he prospected for new seams.

He incorporated the Jefferson Coal Company in the town of Morris, from which he supplied fuel for the first successful coke-fired furnace in the Birmingham District, helping to establish the area as a center of iron and steel production.

Blocton coal earned a reputation as an efficient fuel for steam locomotives and the profitable company embarked on a period of great expansion.

By the summer of 1890 over 3,600 people were residents of Blocton and products from the companies' mines and ovens were being sold to customers throughout the Southeast and parts of Latin America.

He contributed an article to Bulletin 1 of the Geological Survey of Alabama on the state's Eocene fossil record, including nine plates illustrating new species.

As an executive of that company he secured investments that helped TCI survive the depression of 1893, including a contribution of grain and flour from B.

[2] In 1930, the octogenarian Aldrich named new ichnogenera of fossil footprints that were discovered in a University of Alabama coalmine in Walker County, Alabama—his only venture into the field of ichnology.

Although his descriptions were brief, the well-reproduced photographic plates brought this work to renewed attention when similar trackways were discovered in 1999 at the nearby Union Chapel Mine (now the Stephen C. Minkin Paleozoic Footprint Site).
