August Hamann was the fourth child of the clerk in the Prussian War College Christian Friedrich Hamann (1757-1801) and Christiana Friederika Scheidemantel (1775-1813), daughter of a Berlin silk manufacturer . He learned the trade of a locksmith and, supported by Peter Beuth , went to England for further training. There he worked from 1824 to 1829 in the workshop of Holtzapffel & Deyerlein , which was a leader in the manufacture of lathes at the time.

After his return to Berlin, he founded the mechanical engineering company Hamann & Comp with the building manager Richter as a partner. This was located on the property of the building manager Richter at Alexanderstraße 46. In 1836 the company moved to Schillingsgasse 23, Richter is no longer a partner. By 1844 the company had delivered 233 lathes. In the same year 40-50 workers were employed in it. The machine park consisted of 14 lathes, 2 drilling machines and 4 planing machines , which were driven by a steam engine of approx. 5 HP. The company participated in the economic development in Prussia initiated by Peter Beuth . In 1839, the company was given the Borsig steam engine as a gift. Machine tools were also made for other Berlin companies on behalf of the Ministry of Finance.

On March 5th, 1849 August Hamann was granted a patent for a vertical drilling machine by the Prussian state . In 1851 Hamann exhibited a lathe at the world exhibition in London , which was the only machine tool that was not awarded a prize. Hamann supplied lathes to Carl Zeiss and Borsig, among others .

In the course of time, the business premises were expanded to include the neighboring property at Schillingsgasse 24 and the rear property at Kaiserstraße 44/45. After the death of August Hamann, their son Theodor Wilhelm August Hamann (1835–1886) continued to run the company until around 1873, but then sold it to the entrepreneur Jacob Goldmann.
