Mr. Lowenthal graduated with a SB from MIT in Electrical Engineering and Computer Science in 1975, where he was chosen by the faculty as a finalist to receive 'the top thesis' award, and then graduated with an MSEE from RPI in 1976. 

Since graduation he has both developed and managed the development of a very wide range of 'leading edge' hardware, software, and systems products. 

In 1996 he cofounded Terascape. Terascape developed software to manage disks and disk farms and to dramatically increase the performance of Oracle databases. He co-wrote the business plan and obtained venture capital. As VP of Software Engineering he then architected and designed the product, and performed 'hands-on' development while simultaneoeusly managing the development team. Within 4 years sold the company to EMC for approximately $50 million. 

Prior to Terascape - in the roles of a Director of Engineering or a VP of Engineeering - he was at Cambex, ICOT, Alloy Computer Products, Telphi Systems, and Lexidata. 

At Cambex he started the Unix division to develop Unix system utilities and drivers for: tape systems, a variety of single and multiple enclosure disk drive systems, and 'highly available and high performance' disk arrays supporting multiple paths. 

At ICOT he managing the software development of IBM emulation and mainframe connectivity software, and he personally developed: interface cards, a windowed product configuration program, a DMA device driver, the Multi-PU SNA gateway, and S3G graphic display software. 

At Alloy Computer Products he designed IBM personal computer peripherals for tape and disk products as well as a high performance multiprocessor multiuser DOS system. 

At Telphi Systems he was responsible the development of a 'feature rich' telephone PBX that was specifically designed for use in hospitals and the medical community. 

While at Lexidata, in 6 years he was a major force in their rapid growth from less than $800,000 and only 12 employees to $37 million in and over 450 employees. 

His article "Multiprocessors Equip Terminals for High Level Graphics" was published in Electronics magazine in March 1983.
