San Francisco’s historic Hallidie Building

Among the historic buildings of San Francisco is the Hallidie Building, located at 130 Sutter Street, between Montgomery and Keary Streets in the Financial District. It was listed as a Designated San Francisco Landmark in the National Register of Historic Places in 1971.

Though named in honor of Andrew Smith Hallidie, the early promoter of the cable car system, for whom Hallidie Plaza is also named, the building was designed by an equally notable San Franciscan, architect Willis Polk. Completed in 1918, it was Polk’s last major work.

Kenneth Frampton, in Modern Architecture, 1851 to 1945, called the building “the first application of a pure curtain wall to any building in America” (in a glass curtain wall, the glass is hung beyond the structural elements) and a structure of “extraordinary precision and lightness.” While the first claim is disputed—though certainly at least it is among the first—the second should not be. The seven-story facade, traditional in composition and gothic in gold-painted cast iron detail, remains a triumph.

The building was restored for safety reasons in a two-year project that was completed in April 2013. The firm of Page & Turnbull writes of the restoration,

The deteriorated ornamental metal on the 130 Sutter Street façade was of prime concern at the Hallidie Building, which features the first high-rise glass curtain wall assembly in the United States. Deferred maintenance had taken its toll on the façade, and several components were deteriorating, causing water and air leakage, thermal variation on the interior, and an unusable means of fire egress. With the rehabilitation, repairs were made to maximize retention of the historic fabric. This landmark was made new again, including its original blue and gold color scheme, initially selected for its building’s patron, the University of California, Berkeley.

On the same website, Page & Turnbull also provide some stunning photos of the result of the restoration. The building was originally an investment property of the Regents of the University of California.

Anatomy of a flower: the poppy

This close-up of a poppy in Tom’s Garden clearly shows some of the components of the reproductive system of a flower, as well as some of the ways poppies are distinctive.

Crepelike petals account for the red background. In the center of the petals is the stigma, which is the outer element of the pistil, the female reproductive organ. (You can remember this by thinking of the yin/yang dichotomy: pistols are yang/male whereas pistils are yin/female.) The stigma is where pollen germinates.

Supporting the stigma is the style, which grows out of the flower’s ovary. The ovary is a melon-shaped element that forms before petals emerge (when it is covered with sepals, not shown). After fertilization the ovary swells. In opium poppies, this is where the latex is produced that, when dried, becomes raw opium. The stigma, style, and ovary together compose the pistil.

Surrounding the pistil are stalklike stamens (the stalks are termed filaments), capped by lozenge-shaped anthers. The anthers are where pollen is produced. These are the male organs. After pollination, they fall away, together with the wilted petals.

The stalk that supports the entire flower is technically called a pedicel.

Poppies are unusual in usually having just two sepals (many flowers have five) and in usually having four petals (again, more common is five). Likewise, while the most common number of flower stamens is again five, poppies are spectacularly immodest and produce dozens. The disklike structure of the poppy stamen is also distinctive.

Unsurprisingly, given the sedative properties of opium, in the Western tradition poppies are associated with peace, sleep, and death (but also rebirth). But in China, according to Terese Tse Bartholomew in her Hidden Meanings in Chinese Art, the poppy is associated with wealth and honor. In part this is because one Chinese word for poppy, jinbeihua, which literally translates as “brocade blanket flower,” evokes the brocade (jin) that was often worn by ancient Chinese officials.

For this photo I was mainly interested in capturing some of the beauty of the flower in extreme close-up.
