Walburga Stemmer (March 1892–October 1928) was a fruit-seller living in Weingarten (Württemberg) who allegedly had an affair with Erwin Rommel and gave birth to his daughter, Gertrud Stemmer (later Mrs. Gertrud Pan), on December 8, 1913. Rommel turned away from her and in 1916 married another woman, Lucie Mollin.
Stemmer died in 1928, a few months before Rommel had a child, Manfred, with Lucie. Her cause of death is sometimes given as pneumonia though others claim that she committed suicide.
The existence of his second family has emerged in a collection of more than 150 letters and photographs, kept for decades by his illegitimate daughter Gertrud Pan at her home in Kempten, southern Germany.
The letters emerged after Gertrud's death last year. "There were hints from some fellow officers and an army nurse, and was eventually put into the museum curator in Rommel's home town, who confirmed the family's existence," said Sallyann Kleibel, producer of The Real Rommel, to be shown on Channel 4 on August 2.
Rommel met Lucie in 1911 in Danzig. During a temporary posting in Weingarten, hundreds of miles away, he met the teenage Walburga Stemmer, and they had an affair.
In 1913 Gertrud, their daughter, was born, to Rommel's delight. He wrote to Walburga, calling her his "little mouse". He said he would like to set up home with her and Gertrud: "It's got to be perfect, this little nest of ours." However, he returned to Lucie and married her in 1916. Walburga never recovered from her rejection.
Gertrud's son Josef Pan, 62, a fruit and vegetable wholesaler from Kempten, whose family own the letters, said: "Rommel was Walburga's only love. As long as Rommel and Lucie never had children she held on to the conviction that he would return to her. When Manfred was born in 1928 she took an overdose . . . The explanation given in public was that she had died of pneumonia. Later the family doctor told my mother she had taken her own life."
Gertrud exchanged hundreds of letters with her father. She knitted him a scarf, which he wore frequently at the battlefront. Lucie knew about Gertrud, but to Manfred she was always "cousin Gertrud".
She was a frequent visitor to the family and was at Rommel's hospital bedside after he returned ill from Africa. There, she answered the telephone when a furious Hitler ordered him back to Africa, where he was defeated at El Alamein. She stayed close to the family even after her father's death.
