Johanna Friederike Carillon was born into a family originally of Huguenot provenance in the Sachsenhausen quarter of Frankfurt am Main, on the south side of the river. She attended school locally at the "Souchay-Mittelschule" between 1882 and 1889, but received no higher education or training. Her father was a master tailor, and until her marriage in 1899 or 1900 Johanna lived "at home, helping with the housework". Marriage to Richard Tesch, another master tailor, produced in quick succession, three sons.
Political engagement
Following the birth of her youngest son, Carl, in 1902, Johanna began to engage in political activities, initially at a local level. Her political focus lay with the Social Democratic Party which according to some sources she joined in 1902, although others contend that women were not permitted to join political parties in Germany till 1908, and she actually joined the SPD only in 1909. She campaigned for better educational opportunities for working class women and girls: she was co-founder in 1902, together with Lina Heiden and Henriette Fürth, of the "Education Association for Working Class Women and Girls" From 1904 she also worked as a cashier at the Trades Union Office that had recently opened in Frankfurt's "All Saints Street" to provide organisational support for union activities and to operate as a labour exchange. Another focus of her interest was the plight of the many female domestic servants working in Frankfurt: these often suffered from long hours and arbitrary working conditions. In addition, domestic servants were not permitted to join a trades union. In 1906 Tesch founded and became the first Chairwoman of the Frankfurt area "Association of Domestic and Office employees". Later that year, in November, Henrietta Tesch also founded the "Association for Female Domestic Employees", campaigning for the abolition of Germany's prescriptive :de:Gesindeordnung|Laws on Domestic Service and the introduction in the sector of free work contracts. In 1908 she took on the role of cashier, for which she was paid a salary, and in 1911 she took over from Mala Rudolph as Chairwoman of the Association.
War
Johanna Tesch lost her eldest son in the war that broke out in July 1914, but this was not the only reason that during the war she devoted her energies to providing support for the families of war victims. For four years between 1916 and 1920 she worked at the city's welfare office for war widows and orphans, and she also engaged in fund raising for the bereaved. In addition, it is recorded that in 1916 she became a member of the "Municipal Deputation for Lunatics and Epileptics"
National politics
The revolutionary year that followed military defeat was marked by widespread social and political unrest, as well as the abdication of the emperor. 1919 also saw the birth of what came to be known as the Weimar Republic. Johanna Tesch moved from regional activism into national politics. She won a mandate to represent the electoral district of Hesse-Nassau' at the Constitutional Convention which met at Weimar between February and June 1919, producing a new Constitution. Her name was again included on the SPD party list for the national election in June 1920: although the SPD lost a third of its seats, it remained the largest party in the national assembly, and Tesch's name was high enough up on the party list to ensure her :de:Liste der Reichstagsabgeordneten der Weimarer Republik |membership of the Reichstag between 1920 and May 1924, again representing a Hesse-Nassau electoral district'. Parliamentary records show that she contributed to debates on matters that included household welfare legislation and the 1923 budget. The party lost further ground in the election of May 1924, and Johanna Tesch lost her seat in the chamber. By this time she had established a strong reputation as a public speaker, however, and for the next few years she gave public presentations on behalf of the SPD on matters such as housing poverty, taxation policy, educational questions and, ever more, on matters specific to women.
Nazi Germany
Johanna Tesch was a couple of months short of her sixtieth birthday when the Nazis took power early in 1933. Membership of political parties quickly became illegal, and Richard Tesch, her husband, as well as her youngest son, Carl, lost their jobs at the trades union printing works when the SPD party newspaper, :de:Volksstimme |"Volksstimme" was closed down in March 1933. In October 1935 Carl Tesch, who had engaged in trades union training work, was obliged to emigrate to Switzerland. Richard and Johanna Tesch lived on in retirement at their home in Frankfurt's recently built Riederwald quarter. Her former trades union colleague, Paul Müller, had fled to Switzerland in 1934, and later recalled that during 1938 Johanna travelled to visit her son in Switzerland, where she stayed for some months. During this time she was able to have meetings with a number of exiled German trades unionists and with leaders of the Swiss Social Democratic Party. This did nothing to endear her to the German government. But eventually she returned home to Nazi Germany.
Death
On 20 July 1944 an assassination attempt was made against Adolf Hitler. The dictator survived, but the leadership were badly unnerved: the régime had already prepared a list of several thousand names of political adversaries, many of them surviving former left wing politicians from the Weimar era, to be used in the event of an escalation in political tension on the home front. The name of Johanna Tesch was on it. She was arrested on 22 August 1944 and taken to the concentration camp at Ravensbrück. By this time her second son, Wilhelm Tesch, had already been killed in the war. Fellow inmates recalled that from the concentration camp she was permitted to write to her family regularly, using her letters, which were naturally subject to SS censorship, to reassure them that she was well. Nevertheless, she had been suffering from serious heart and kidney illness at the time of her arrest and her husband had been struggling, without success, to obtain her release on grounds of her poor health. Roughly 6 months later, on 10 March 1945, fellow inmates got hold of a pen and paper for her, and Johanna Tensch started to write her fare-well letter. Three days later she died, probably from a combination of the medical conditions from which she had been suffering at the time of her arrest and the malnutrition which was endemic in the concentration camp.
