Steinway Model O
Living Room Grand

Steinert Overview

This was the first of the Steinway “Miniature” grands–O (5’10 3/4”), M (5’ 7”), L (5’10.5”)– manufactured before the Great Depression and all designed by one man–Henry Ziegler, the son of Doretta Steinway Ziegler, the daughter of Henry Steinway, the founder of Steinway & Sons.  Henry Ziegler was a design genius that perfected the largest Steinway also created most of the smallest Steinways. Steinways have no cousins, only siblings.  The reintroduction of the round tail Model O in 2005 (replacing the 5’10” Model L) has delighted pianists with its balanced tone. rich bass and ultra-responsive action.

The New Model O Customer

Who it’s for: Who it’s NOT for:
For the more discerning amateur or professional teacher who must have the beginnings of the true “grand sound”.  Not for restricted spaces that can only accommodate an S (5’1”) or M (5’7”) and for those who want the smallest Steinway that still gives the impression of a larger Steinway in the bass, tenor, and treble projection and power.

The Model O & Steinert History

The Model O(5’10”) was introduced in 1900. Only 3 years earlier, in 1897, Alexander Steinert called the Bryant & Stratton Business School, and asked them to send their brightest young bookkeeper for an opening in the Boston store. Jerome F. Murphy, 16, answered the call and started at the Steinert office on January 14, 1897 at a salary of $6.00 per week.

During the great depression, the Murphy family acquired M. Steinert & Sons and still runs it today.
