Jesse Besser (1882–1970) was an inventor and manufacturer from Alpena in the U.S. state of Michigan.He is best known for inventing, and supervising a series of improvements to, a tamping machine used to rapidly press wet, flexible concrete into blocks, thereby making possible a new generation of applications in masonry construction.
Accuracy: Panels and blocks made of autoclaved aerated concrete are produced to the exact sizes needed before leaving the factory. There is less need for on-site trimming. Since the blocks and panels fit so well together, there is less use of finishing materials such as mortar.

I also believe it would be helpful to mention their modularity with brick sizes. In the US one CMU block is both the same width and depth as two bricks plus a mortar joint.
Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths.
The original Besser block machine is on display at the Besser Museum. Herman Besser was involved with the Alpena Portland Cement company. In 1904, his son, Jesse Besser, developed the first hand-tamp block machine. This technology ‘revolutionized the block-making industry” and the Besser Company was born.
Also called building tile, structural terra cotta, hollow tile, saltillo tile, and clay block, the material is an extruded clay shape with substantial depth that allows it to be laid in the same manner as other clay or concrete masonry. In North America it was chiefly used during the late 19th and early 20th centuries, reaching peak popularity ...
