If anyone is interested in listening to her music, this lovely album has all the currently-known surviving songs she wrote, and is well worth a listen! open.spotify.com/album/0jcL7u...

Thanks for putting this together! Would love to be added if you don’t mind :)

In this 3rd page of the report, you can see the references on which D Kayser worked with A Djourno that are relevant for the device implanted in 1957, indicating that she had contributed to the work background over multiple years. Unfortunately I don’t know anything else about her, but she existed!

D Kayser is listed on this and the previous report of the first cochlear implant (in March 1957 in Paris) as providing technical collaboration. Many women at the time were unable to complete PhDs of their own and worked in research labs as “Research Technicians” in order to be involved in science.

We also observed an unexpected effect where artificially increasing current spread (“blurring”) caused an increase in current spread towards the apical portion of the arrays, but not when applied toward the basal portion - possibly as a result of cochlear anatomy

I highly recommend a read of the book “Colonised Minds: Narratives that Shape Psychology” released earlier this year and that he co-authored with @eerobbins.bsky.social. Check it out here: uk.sagepub.com/en-gb/eur/co...
