Wilson Sonsini Goodrich & Rosati took Brocade Communications public on May 25, 1999. The shares were priced at $19 — seen as a good deal at that time because Brocade was actually swinging a profit that year, when so many tech companies going through an IPO were not.

The shares were an even better deal for Larry Sonsini, Wilson Sonsini’s name partner: He held pre-IPO options to buy more than 100,000 shares priced at $5, according to public filings with the Securities and Exchange Commission.
