Viktor E. has the certificate
Under Source Notes the entry says only "Birth certificate in hand from Viktor E." and gives a single time, so one chart is drawn here.
Wikipedia names Santa Monica as his birthplace, while the entry records Redondo Beach. This page follows the entry.
| Point | Sign at birth | In that sign | Before and after |
|---|---|---|---|

Rising sign, midheaven and Moon calculated by us, Redondo Beach, California, Pacific Daylight Time (UTC-7).
Venus 6°33′ past the ascendant, 0°49′ short of Leo
Venus at 29°11′ of Cancer sits just behind the point where the chart begins, and both Placidus and Whole Sign call that the 1st house. Venus stands for affection and taste, and Cancer adds protectiveness; placed this close to the ascendant, it is read as warmth that others notice early.
Only 0°49′ remain before Leo. Astrologers call this a last-degree placement and read it as a theme at its fullest, close to moving on. Venus sextiles Mercury, 2°11′ off, and trines Neptune, 3°08′ off.

Mercury and Uranus, 1°11′ apart, with Jupiter near the IC
The IC is the low point of the chart, standing for roots and what lies behind a public life. Here it is 9°52′ Libra. Jupiter at 7°29′ lies 2°23′ before it, with Mercury at 1°22′ and Uranus at 2°33′ further back in Libra. Mercury and Uranus form his tightest aspect.
Mercury's thought and speech joined to Uranus's sudden turns are read as quick, unconventional thinking; Jupiter widens whatever it touches. Libra's ruler is Venus, the planet beside his ascendant. Placidus gives the trio the 3rd house, linked with talk and errands, while Whole Sign moves them into the 4th, the home ground.

Pisces Moon, squared by Mars within 1°40′
The Moon at 18°13′ of Pisces and Mars at 16°33′ of Sagittarius stand a quarter of the zodiac apart. Astrologers read a Moon-Mars square as feeling and drive pulling against each other, here between the sea of Pisces and the open road of Sagittarius. Jupiter rules both signs and stands in Libra near the IC.
The Moon entered Pisces at 9:04 p.m. on August 26 and leaves for Aries at 10:58 p.m. on his birthday. Both systems put it in the 9th house, the house of long journeys and higher learning. Mars falls in the 5th by Placidus, the house of play and performance, and in the 6th by Whole Sign.

Cancer until 3:39 a.m., with Aries overhead
Cancer held the horizon over Redondo Beach from 1:21 a.m. to 3:39 a.m., and he arrived 103 minutes into that window. Leo takes the ascendant at 3:40 a.m. A Cancer ascendant is read as a guarded, caring first impression.
The midheaven is 9°52′ Aries, which Aries reached at 2:28 a.m., 36 minutes before the birth. Aries there suggests a public manner that starts things and moves first, and its ruler Mars is the planet the Moon squares.

Virgo Sun, trine Saturn 3°59′ from exact
The Sun at 4°55′ of Virgo trines retrograde Saturn at 8°54′ of Taurus, an earth-to-earth link that the tradition reads as steady, practical effort. By Placidus the Sun falls in the 2nd house, the house of resources and skills, and Saturn in the 10th; Whole Sign shifts both one house on.
Mercury rules Virgo, and here Mercury stands in Libra beside the IC, away from the Sun. Earth, water and air hold three planets each, and Mars alone is in fire.
