IN MEMORIAM: SJOERD MAYER
Sjoerd Mayer studied mathematics on the University of Enschede in
the Netherlands. In those days (1970’s) computers were introduced to
universities, and Sjoerd, in his 20s, was already exploring new possibilities
of combining his hobby, birdwatching, with mathematics. According to him it was
possible to store a sound of a bird on a computer. He once proudly showed his
birder friends a floppy disc that contained the sound of a bird, according to
him. He could not prove it because the mainframe computer in the basement was
not able to play sounds. But Sjoerd was convinced there were possibilities in
doing 'something' with birds and computers.
After his study (cum laude) and military service, Sjoerd was asked
to work for the Natlab of Philips in Eindhoven. He
was taught to write computer programs and after having worked writing software
for a few other companies, he decided to work independently writing software
for third parties. Sjoerd made a good living, and he decided to combine his
work with traveling. He made long, strenuous trips of sometimes several months
to countries like Nepal, the Philippines, and Bolivia.
Bolivia stole his heart, and in the late 1980s Sjoerd decided to live
partly in Santa Cruz. He roamed Bolivia,
but also lived in Holland part-time with his mother. In the beginning he lived
with his friend Bernard Geling in Santa Cruz, who
accompanied him on several exciting trips. In the early 90s Sjoerd started
recording sounds of birds on cassettes with a Sony professional Walkman. He
spent many hours recording birds in the field and at home replaying the sounds and
annotating the information in small notebooks. He had a tremendous skill for
remembering the sounds, and soon he discovered that the songs of the birds were
very important in identifying the species, sometimes more important than the
illustration and description in the field guide.
Sjoerd always kept his computer knowledge up to date by writing
software for companies such as the Dutch Railway (NS). In Santa Cruz he bought
computer magazines from the small newspaper stands on the street. One day in
1994 he read an article about using music on computers. He came up with the
idea of importing his sound recordings into a desktop computer. Because there
was not much sound software around, Sjoerd started writing his own computer program
using his programmer skills. When his friend Bernard saw what he made, he
immediately saw possibilities selling CD-ROMs with sounds of birds to the
birders visiting South America.
In 1995 Sjoerd and Bernard decided to start the company Birdsongs
International. Their goal was to sell sounds of birds to the public; their
first publication would be about the birds of the country where both their
hearts were: Bolivia. Sjoerd went on
to record the sounds of as many bird species as possible in Bolivia, while
Bernard was doing the paperwork to found the company in the Netherlands. In
December 1995 Birdsongs was legally established, and soon the first publication
on a CD-ROM became available named "Bird Sounds of Bolivia/Sonidos de Aves
de Bolivia version 1.0". Sjoerd made all the recordings and wrote the
software. Bernard was the man in Holland who did the reproduction, sales,
shipping and administration of the small company.
Although the sales figures were not high, the innovative product was
well received in the birding community. Birders with collections of sound
recordings on tape wanted to cooperate.
Some contributed their recordings to the Bolivian project, and others
asked Sjoerd to make new publications. Peter Boesman produced with "Birds
of Venezuela", Jelle Scharringa
made "Birds of Tropical Asia”, and Niels Krabbe and Jonas Nilsson produced
"Birds of Ecuador". Sjoerd added illustrations and ingenuous
distribution maps (Tropical Asia).
He continued to develop software, and soon second DVD-ROM editions were
made and even a third DVD-ROM edition for Tropical Asia was published.
To sell the products internationally, Sjoerd made a website where
birders from all over the world could buy the products. Again he showed his
software talent by making a fully functioning web shop with shopping basket,
credit card payment feature, etc. several years before web shops became
mainstream ways of selling products. Developing new bird song productions took
more time then expected, and costs were soaring. The web shop had only a few
products, and to boost sales Sjoerd and Bernard decided to start selling other
sound productions. The French recordist Jean Roche cooperated by selling his
CDs of the Birds of France in their shop. Soon several other recordists added
their CDs, and the web shop became well known in the international birding
community.
In the early 1990s Sjoerd started complaining about a numb leg
during his strenuous bird trips he made in the jungle and mountains of Bolivia.
He went to see a physiotherapist, but it did not solve complaints. On one of
his periods in Holland in 1996 he went to see a doctor who diagnosed Multiple
Scleroses. It did not stop him from going to Bolivia: the very next day after
the doctors gave him this very bad news, he was on a plane to Bolivia. He was
in love with a lovely young Colombian girl named Nieves, whom he met in Santa Cruz.
They decided to marry and live in Cochabamba, where their first child was born.
Unfortunately, Sjoerd's health deteriorated faster
than expected, and for medical reasons they had to go and live in Holland.
Once settled again in the Netherlands, Sjoerd decided to devoid all
his working time to developing his software and selecting sound recordings. He
spent many hours listening to recordings that other sound recordists sent to
him. His desk was littered with hundreds of tapes to which he listened extensively
and from which he made meticulous cuts that could be used on a new version of
his 'Birds of Bolivia'. He had enough material to cover the sounds of nearly
all the birds of Bolivia, southern Peru, and Paraguay, a production that
unfortunately has never been published.
Sjoerd's health was deteriorating, and the family was forced to move to a
specially adapted house where Sjoerd got his own room in which he could move
freely with his wheelchair. After roaming much of South America, he now divided
his precious remaining time between his computer room with his sounds and the
living room with his wife and kids. To become eligible for income security for
his years left, Sjoerd was forced to give up Birdsongs International, to his
great regret. MS was affecting him in a bad way physically as well as
emotionally.
At the end of his life Sjoerd decided to make drastic decisions,
clearing up his adventurous life he decided to throw away everything of his
past, literarily in a dustbin. Done with that, he started seeing off his best
friends, sometimes in a not such a nice way. He isolated himself from the
outside world and devoted more and more time to his family. He was very lucky
in having a wife like Nieves, who helped him all she could. The last words on Sjoerd's website were more then true: "I'd already be
in a nursing home by now if it weren't for my brave wife Nieves. The show is
(almost) over!"
Sjoerd Mayer was co-founder of Birdsongs International, the company that
developed and sold CD- and later DVD-ROMs of Bolivia, Venezuela, Ecuador, and
Tropical Asia.
