A Name Returns to the Stage

An orchestra. A family. A name spoken again.

Last night, The Wonderful Wertheim Symphony had its world premiere at the Bulgaria Concert Hall in Sofia, performed by the Sofia Philharmonic Orchestra under Nayden Todorov. The applause lasted for minutes.

Few in the hall knew what they were watching. On the balcony, Carlos Guilliard, descendant of the forgotten industrial Wertheim dynasty, heard this musical monument to his own family for the first time.

The Wertheim name had not been spoken in public for the better part of a century. Last night, an orchestra spoke it for him.

Long after the heritage had seemingly been erased, Guilliard stepped into his forefathers' footsteps: generations who used culture to give back to society, and music to connect minds and cultures.

"Some stories end in silence. This one came back to life last night in Sofia and is to be continued."

The second half of the programme presented the world premiere of The Wonderful Wertheim Symphony by Roland Baumgartner, commissioned by Carlos Guilliard and his long-time team.

About the Symphony

Inspired by the history of the Wertheim family, the symphony explores universal themes of innovation, family, resilience, displacement and legacy. Rather than recounting historical events chronologically, it reflects on the lasting human impact of one family's contribution to European society.

About the Composer

Roland Baumgartner is an internationally recognised composer whose work spans orchestral, chamber and vocal repertoire. The Wonderful Wertheim Symphony is the result of several years of research and collaboration surrounding the rediscovery of the Wertheim family's history.

About the Wertheim Family

Joseph Wertheim founded his sewing machine business in Frankfurt in the early 1860s, with a sales branch in Barcelona (1870), following his return from the United States. With remarkable foresight, his son Karl founded Rapida S.A. in Barcelona in 1920 under the name Don Carlos Vallin Ballin, carrying the family's industrial legacy into Spain.

This took place at a time when the first anti-Semitic movements were becoming active in Germany — movements that culminated in 1932 in the closure of the 600-strong factory in Frankfurt and ultimately in the expropriation of the family. Like so many Jewish families of that era, the Wertheim family too fell victim to the persecution of Jews: in 1938, Karl Wertheim's brother Paul — formerly head of the Frankfurt factory — took his own life under the weight of the closure and expropriation; in 1941, his brother Franz was murdered by the Nazis; and Karl Wertheim's nieces, including Ilse Minna Rosalie Hesselberger (née Wertheim), were arrested between 1941 and 1944 and perished in one of the many concentration camps.

Other family members succeeded in escaping to Australia. Although the family name gradually faded from public consciousness, its contribution to European industrial and social history continues to resonate to this day.

The Machine That Changed the Lives of Millions of Women

A forgotten European dynasty. A remarkable true story. A new symphony.

Imagine a European home in the late nineteenth century. A mother sits at her sewing machine while her children practise the piano nearby, the rhythmic sound of needle and thread mingling with the music filling the room. For millions of families across Europe, this became the sound of hope, though few today remember the family behind it.

On 10 September 2026, that story returns to the public stage in the world premiere of The Wonderful Wertheim Symphony, performed by the Sofia Philharmonic Orchestra under the direction of Nayden Todorov. Commissioned by Wertheim descendant Carlos Guilliard and composed by Roland Baumgartner, the symphony tells the extraordinary story of a family whose influence reached far beyond technical innovation.

That story begins with Joseph Wertheim. On 5 May 1862, a modest newspaper advertisement appeared in Frankfurt announcing him as General Agent for Wheeler & Wilson sewing machines at Fahrgasse 108. Few could have imagined that this small notice marked the beginning of one of Europe's most influential sewing machine manufacturers.

The machines that followed entered homes across Europe, South America and later Australia, carrying with them more than mechanical innovation. At a time when a single dress could require up to forty hours of hand sewing, the sewing machine transformed productivity. It let women build businesses from home, contribute more substantially to family income, and produce clothing at a scale that had previously been impossible. It also helped make quality garments accessible to ordinary families and helped grow an industry that still employs millions of women around the world.

The story did not end in Frankfurt. As the first anti-Semitic movements emerged in Germany, Joseph Wertheim's son Karl began expanding the family's activities to Barcelona. Under the name Carlos Vallin Ballin, he founded Rapida S.A., a company that became part of the city's industrial history. Across two countries and several generations, the family quietly shaped lives far beyond their own, even as history preserved the machines more faithfully than the people who created them and the Wertheim name gradually faded from public memory. Its legacy did not.

"When I first encountered the history of the Wertheim family, I realised this was not simply a story about industry. It is a story about human ingenuity, resilience and the quiet ways in which innovation can change everyday life." — Roland Baumgartner

The Wonderful Wertheim Symphony forms part of a broader effort to rediscover that legacy, alongside ongoing historical research, a forthcoming documentary, a book and the restoration of the family's historic home in Frankfurt. Together, they invite audiences to reconnect with one of Europe's remarkable yet largely forgotten industrial stories.

Some revolutions are announced with fanfare. This one began with a single stitch.
