allow the counsel himself to make disclosures of confidential communications from his client; but if the client sees fit to be a witness, he makes himself liable to full cross-examination like any other witness’; and it was said in Gossman v. Rosenberg, 237 Mass. 122, at page 124, ‘a voluntary witness waives every personal privilege.’ The privilege against the disclosure of confidential communications between attorney and client is personal to the client and may be waived by him. Phillips v. Chase, 201 Mass. 444, 450. See Montgomery v. Pickering, 116 Mass. 227; McCooe v. Dighton, Somerset, & Swansea Street Railway, 173 Mass. 117. The evidence was admissible. The exception argued must be sustained.” Id. at 196.

Paxton & Gallagher Co., 83 Neb. 88, 92, 119 N. W. 14 (1908) (“We think that, when the plaintiff testified to a conversation between himself and his attorney, he waived the privilege of such attorney, who thereupon became a competent witness to testify concerning the matters already disclosed in open court by his client.
