Famous Danish Inventions: The Loudspeaker

Did you know that it was a Danish engineer who invented the first Loudspeaker?

Peter L. Jensen was that man.  He was a prolific Danish inventor and entrepreneur.



Jensen was born in 1886 and began his engineering career at the laboratory of Valdemar Poulsen, the inventor of magnetic recording.  He became an assistant to Poulsen and was later sent to the US to introduce the Poulsen Radio Arc System and then took a job with the Federal Telegraph Company in California in 1910.

A year after the move, he founded the Commercial Wireless and Development Company with Edwin S. Pridham and Richard O’Conner which later became the Magnavox Company, he stayed there until 1925.

Together with Edwin S. Pridham he built the first moving coil loudspeaker in 1915 and in 1916 he built and patented the first contained and complete electric reproducing phonograph. Next, Jensen made the first public address system which he unveiled on Christmas Eve, 1915 in San Francisco. 75,000 people were present and heard all the speeches and announcements through the system. The systems, called Magnavox, were later used all over the US, even President Woodrow Wilson used the system in 1919. In the same year Jensen designed the Magnavox dynamic loudspeaker for reception of radio broadcasting.

Additionally, Jensen invented and patented, with Edwin S. Pridham, the first anti-noise self-neutralizing microphone in 1917.  The microphone allowed wireless communication between aircrafts and the ground. It later became known as the lip microphone and was widely used in both World Wars.

In 1927 Jensen founded the Jensen Radio Manufacturing Company, marketing speakers under the trade name Jensen. He headed up the firm until 1940 and in 1945, he founded Jensen Industries Inc. which manufactured phonograph needles and later, the stainless steel sink.

Jensen was hugely respected in his lifetime and was made an honorary Member of the Audio Engineering Society in 1955. He was elected an Extraordinary Member of the Danish Engineering Society, and Jensen was knighted by the King of Denmark.

Great Danes: Nikolaj Frederik Severin Grundtvig


N.F.S Grundvig was a busy guy; he was a pastor, author, poet, philosopher, historian, teacher and politician (he was also married 3 times, where did he get his energy from?).  He was an extremely influential Dane and his ideas still have a bearing on what it is to be Danish today.  He, and his followers, are often associated with the formation of the modern Danish national consciousness.

The Carlsberg Visitor Centre

The rain was pouring in Copenhagen and my sister and I decided a trip to the Carlsberg Visitor Centre was in order.


Both my parents had fond memories of their visits many years before – mainly due to the bottomless free bar which used to be available, and had recommended a visit.  There are still a few free drinks you can enjoy and you can sample the more adventurous Carlsberg variants too.

Knowing very little about Carlsberg, other than its familiar taste, before the trip – I was surprised to discover its long and intriguing history filled with family feuds, stiff competition and jaw dropping philanthropy.

Hej readers,

As you know I am a keen fan of many Danish TV series but I am yet to watch a lot of Danish films.  Now I am enlightened, ‘A Royal Affair’ was a great place to start.  I love a sumptuous costume drama and it is fitting that the heroine travels over to Denmark from England and has to adapt to life in a new country.

A Happy New Year Danish Style

Festive greetings readers!

I hope you had a lovely Christmas and are enjoying 2015.  I thought I would celebrate the dawn of the New Year by cooking a Kransekage to share with my cousins during our festivities.

As discussed previously; a great chef I am not, as you will again discover, but I have had fantastic help from a great Danish cooking blog I found through Twitter: Nordic Food Living – oh and wine, lots of wine, Danish binge drinking style.

Christmas Celebrations in Denmark. Glædelig jul!

Hej readers,

I am of the heavily over enthusiastic, carol singing, hideous jumper wearing school when it comes to Christmas.  As I enjoy the festive tunes, sip my delicious mulled wine and chomp away through my Christmas calendar, I often ponder how my Viking friends across the sea celebrate my favourite date of the year.

It didn’t take much of a stretch of the imagination to guess that the Danes go all out on the hygge front and that Dannebrog, being a handy match for Christmas colours, is integral to home decor.
