Rosalia Graf (born Rosalia Moser: 1 June 1897 - 21 June 1944) was an Austrian domestic servant and factory worker who became a resistance activist some time after the incorporation of Austria into an enlarged version of Germany in March 1938. On 14 April 1944 both she and faced trial and were convicted of "preparing to commit high treason". They were sentenced to death at the recently reconfigured . On 21 June 1944, within a few minutes of one another, they were executed (along with fourteen others convicted on similar charges), using the guillotine in the in another part of the extensive court complex.
Rosalia Moser was born in Breitenbrunn/Fertà Âszéleskút, the daughter of Mathias Moser, a small-scale farmer, and his wife, Elisabeth. Breitenbrunn, then as now, was a small village located by the marshy northern foreshore of the Neusiedlersee/Fertà  (Lake) in the ethnically conflicted Burgenland/Gradià ¡ÃÂe/Felsà Âà Ârvidék region. At the time of her birth it was within the Austro-Hungarian empire, part of the Kingdom of Hungary (though it would in 1922 pass to the newly reconfigured Austrian Republic following a referendum). School attendance was compulsory: Rosalie Moser attended local school for the stipulated period and then took work as a domestic servant, working at different stages in Hungary and Austria. At some point she relocated to Vienna, becoming an unskilled factory worker.
In 1930 Rosalia Moser married , who had grown up in Vienna, and was working for the city authorities. Rosalia was almost ten years older than her husband. According to later court documents, the marriage was childless. They made their home in an apartment at JohnstraÃÂe 34/36 in Vienna's west-central Rudolfsheim-Fünfhaus quarter. By 1934 Johann and Rosalia Graf were both members of the Social Democratic Party. 1934 is of particular significance as the year during which the Social Democratic Party was outlawed, as part of a broader political transition to what came to be known as "Austrofascism". Any further political involvement by the Grafs would have taken place, as far as possible, "beneath the radar" at the time: court documents submitted in the context of the couple's prosecution in 1944 assert that they continued to use the apartment for "political discussions", notably involving their friends and fellow resistance activists Anton and Emilie Tolnay. The intensity of the "political discussions" increased after the invasion of Poland in September 1939 triggered the outbreak of war, and discussions intensified further in June 1941 when a massive German invasion of the Soviet Union indicated that the implausible non-aggression pact between Berlin and Moscow was over. In June 1941 and Rosalie Graf announced to comrades their "membership" to the (illegal) Communist Party and, as a sign of solidarity, made their apartment available as accommodation for party comrades needing a safe house, and for clandestine party meetings.
During the night of 1 May 1942 the Grafs took part in a leafleting campaign: this will have involved distributing copies of politically incendiary information sheets in public places, such as park benches, public toilets, train stations, trams and tram stops. Surveillance of government opponents by the security services in Vienna had become ever more effective, and it is likely that the authorities were already aware of the Grafs' opposition activities, but detailed investigation into the provenance and distribution of the anti-Hitler leaflets will have increased their knowledge and the extent of the surveillance to which the couple were subjected. The wording of the leaflet reads like a calculated attempt to provoke the authorities:
Slightly more than ten weeks after the leafleting incident, on 15 July 1942, Johann and Rosalia Graf were arrested on "suspicion of preparing high reason". Their details were recorded, they were photographed and they were interrogated by the Vienna Gestapo. The brought charges against them at the special People's Court on 22 December 1943. Following conviction, they were sentenced to death on 14 April 1944, found guilty of "preparing high treason and advantaging the enemy". Others sentenced to death by the People's Court at the same hearing included Emilie Tolnay and , whom the authorities had also identified (correctly) as anti-government resistance activists with communist beliefs. (Emilie's husband, Anton Tolnay received a ten-year jail term (but was released a year later when the régime collapsed).
On 21 June 1944 Johann and Rosalia Graf were led to the killing table in the of the where they were executed on the guillotine within a few minutes of one another. They were included in a batch of 16 execution victims killed (some sources use the word "murdered") by the Hitler state on that occasion. Others included their co-accused, and the brothers and . Emilie Tolnay underwent the same fate a few days later, on 5 July 1944.
