In commemoration of the 20th Anniversary of 9/11, Ed Zier and Koehler Books have published UNDAUNTED.  
It is the true story of an entrepreneurial success and its fortitude through the tragedy.

Without warning the Twin Towers were viciously attacked.


Thousands were murdered. The people of Baseline—high in the South Tower—faced critical, life-dependent decisions. Four colleagues tragically lost their lives.

The dramatic evacuations by Baseline associates, and their resolve...


…to rebuild the business, while focusing on all its stakeholders, was greatly facilitated by the well-developed, team-oriented corporate culture of this entrepreneurial success story.

On September 11, 2001 Baseline was in the midst of its greatest growth spurt.


“I don’t think I have ever met one investment professional who didn’t marvel at the brilliant and elegant simplicity of Baseline. It was one of the first investment applications I ever learned and I have always judged other applications against it for ease of use.”
Mark Weiss, Chief Investment Officer of Virtonos Capital
