In public discussions it's generally best to use Danielle Berry, the name she chose. This respects her identity, provides accurate historical context, and importantly, offers a role model for those exploring their own gender identity.
It also fosters 'trans literacy' - understanding and respect for trans identities. As a fan of both Wendy Carlos and Danielle Berry since childhood, I've not only had the chance to enjoy their boundless creativity but I also learned so much in addition to that.
Shouldn't she / we all have our individual rights respected on these matters - the power over how to define one's own identity, both in life and how we are remembered after death?
As a fellow fan, I try to respect her autonomy and honour her legacy by using her chosen name: Danielle (Bunten) Berry.
