Lenz was born to a Prussian and devoutly Lutheran notary in Greifswald, Province of Pomerania.

He served in the 1870-1871 Franco-Prussian War and was wounded in the Battle of Villiers. He then continued his studies, at first in Greifswald for one semester, and then in Berlin. In the following year he started working for the secret state archives in Marburg with the duty of editing the correspondence of Philip I, Landgrave of Hesse.
lieutenant would be published in three volumes from 1880 to 1891.
Meanwhile, he also wrote his habilitation about the Council of Constance, which he finished in 1876. In 1888, switched to the University of Breslau and in 1890 to Frederick William University in Berlin.
Alongside Hans Delbrück, Dietrich Schäfer, and Gustav Schmoller, he became one of the most important historians in Berlin. Unlike those other three, he avoided involvement in political matters and thus had more difficulties securing his influence.
A supporter of the methodology of Leopold von Ranke, Lenz advocated complete objectivity and neutrality in the study of history.
In Berlin, Lenz continued to study the Reformation, publishing works about Gustav Adolf and Albrecht von Wallenstein, but he also started devoting his attention to other epochs, such as the French Revolution, the Napoleonic era, and the early German Empire. He thus published a biography of Otto von Bismarck in 1902. In 1911, Lenz became the director of the history faculty, from 1911 to 1912 he was the rector of the university.
In 1914, he moved to the Colonial Institute in Hamburg and was a key figure in its transformation into the University of Hamburg.
In 1922, Lenz went into emeritus and moved back to Berlin, where he died.
