Who is Kalman Brattman? He is NOT Kalman Filter

Kalman Brattman is NOT the Kalman Filter

WE HAVE THE PROOF!

The Kalman Filter is fully described in here. No reference to Kalman Brattman is to be found.
The Kalman Filtering concept is presented in some detail in here. No reference to Kalman Brattman is being provided.
Kalman filter toolbox does not contain any reference to Kalman Brattman.
Why Brattman has acquired the name Kalman is not clear and perhaps is misleading.
There is an Unscented Kalman Filter for Nonlinear Estimation thai is a subtle concept but again the important point to be made is that Kalman Brattman is not associated with any variety of the Kalman filter. Why Brattman has acquired the Kalman name is a question with no answer as it cannot be associated, for sure, with the Kalman Filter. So, Who is Kalman Brattman? Why Kalman and Brattman are being associated?
